Is cracking the coding interview still relevant 2020. Is unique cracking the coding interview. How long does cracking the coding interview take. Cracking the coding interview pdf 2020. How is cracking the coding interview.You can set yourself up for success and nail your next coding interview. This isn't a set of "hacks", "tricks", or some kind of brain dump. Don't use sneaky tactics or tricks to crack your way into a position you aren't qualified for. Follow this path and you will nail the interview because you'll be a better developer. Take a course on Computer Science 101from Stanford, for free. It's super helpful to know this. Take a high-level view of each and some courses will help you absolutely dominate in this area: Algorithms and Data Structures.The room is silent except for the buzzing of the fluorescent lights. The judges across the table are staring at you, expressionless. Some have pen and paper, some don't.They're all staring at you. Your mouth is so dry it feels like you've been eating sawdust all day. You grab the marker and head for the whiteboard. One judge is staring at a laptop. It's time to show them a quicksort.I've been on both sides of the coding interview. I've interviewed for jobs, sometimes I got the offer, sometimes I didn't. Sometimes I nailedthe whiteboard tests and didn't get a call, and vice versa. I've interviewed probably hundreds of people in my career and I did my best to make candidates feel comfortable, but many managers won't. They will try to trip you up, make you choke. We can argue about the effectiveness of a whiteboard interview later, but they will happen.Let's look atsome tips to rock your next coding interview. You can set yourself up for success and nail it. Don't be mistaken, this isn't a set of "hacks", "tricks", or some kind of brain dump. Don't use sneaky tactics or tricks to crack your way into a position you aren't qualified for. They'll just fire you later. Follow this path and you will nail the interview becauseyou'll be a better developer.What They're Looking forHere's what most of the interviewers will be looking for, in no particular order: Problem Solving - How well can you solve problems, and more importantly: what is your process. Many tests will look for this. Coding Skills - You'll need to be ruthlessly good here. I've handed people laptops and toldthem to write something for me. You can tell how much actual coding people have done by watching them do it. Technical Knowledge - This is where the trivia questions come in, but your interviewer wants to know just how technical you are. Experience - This is where you talk about your past projects. Interviewers want to hear your war stories, andwhat you learned from them. Culture Fit - I can't help you much with this one. This is where they see how you'll fit into a team. There are ways you can improve in this area.So what do you need to do to get prepared? Let's dive in. Stage 1: Laying the FoundationSo here's what you need to be doing way before any interview. Days, months or weeksbefore you need to build some core skills. Learn Computer Science BasicsYou need to get the basics of Computer Science down. You don't have to be Donald Knuth here, but you need to know the theory, language, and idioms. This is the bare minimum for an interview. If an interviewer starts casually mentioning a binary tree in the interview youbetter know what they're talking about. Review The Basics of Computer Science Tutorial - some of this may be pretty basic to you but it gives you a framework of things to pay attention to. Where do your strengths lie? If you find any areas where you are weak at, work to build your knowledge and skills in that area. Review Teach Yourself ComputerScience - Again we're talking basics foundational stuff that you may be lacking in. You need to know the basics and speak the language. You can even Take a course on Computer Science 101 from Stanford, for free.Learn Different AlgorithmsAlgorithms run the world and if you're a developer you'll need to know them. So how do you get good atalgorithms? It's not black magic or a secret art. According to Geeks for Geeks these are the top 10 algorithms in interview questions:GraphLinked ListDynamic ProgrammingSorting and SearchingTree / Binary Search TreeNumber TheoryBIT ManipulationString / Array It seems pretty accurate to me. It's super helpful to know this. What are you greatat in this list? What are you weak at? This link is excellent for getting a high-level view of each and some examples. These courses will help you absolutely dominate in this area:Algorithms and Data Structures - Part 1Algorithms and Data Structures - Part 2In about 6 hours you'll be able to understand and really talk the talk when it comes toalgorithms. Action: Study this stuff. Learn it. Know it.Stage 2: Practice Practice PracticeHere's another thing you need to make a part of your routine: practice. You need to practice this stuff a few times a week or more to really get good. The more you practice the better you'll do in any whiteboard situation. Most of the time they ask for pseudo-codebut if you really put your practice in you can write real compilable code on a whiteboard without blinking. Check out the HackerRank Interview Preparation Kit - This is where the rubber meets the road with all that algorithm knowledge you now have. Put it to work with real examples. Start participating in HackerRank Challenges - This is how youcan really apply your knowledge in different areas. This is the ultimate whiteboard practice area.It's broken down like this:- Algorithms - Data Structures - Mathematics Do an exercise a day when you can. Work your way through many of the challenges. If you just do a challenge a day for 30 days you can nail a whiteboard interviewand will become a better coder. I promise you. Sign up for LeetCode and start participating in challenges - Nothing sharpens your skills like competing with others. There are tons of challenges and fun stuff here. Check out Project Euler and start writing code to solve the problems there. Project Euler is a set of math and programming problems thatreally challenge your problem-solving abilities. Use code to solve your problems here and your skills will grow. Action: Write some code. A lot of it. Get ruthlessly good at it.Stage 3: Build Your Public ProfileYou need to have work you've done online and accessible. Every recruiter, manager, or someone interested in you will Google you. Make sure theyfind your work. Put your stuff Online and start a GitHub account if you don't already have one. Put all of your code up there. Your personal projects, stuff you write for tutorials, all of it.Create accounts on sites like JSFiddle and CodePen - This is mostly for web developers but it creates a good spot where people can find your work. Create a Blog - Itdoesn't matter if it's WordPress, GitHub pages, or a custom hosted server setup like my blog you should create a blog that talks about what you're working on, what you're learning, and what you can teach. Note: I have thrown away resumes of people when I couldn't find their GitHub or any public work. This shows that they aren't enthusiastic andmanagers who look for passionate people will look for what you've posted publicly. Put your work out there no matter how good it is. Action: Sign up and start making your code and projects public.Stage 4: Prepare for InterviewsPreparation ultimately determines your success. Nobody succeeds without preparation. Here's how you can prepare foryour interview and kick the ball through the uprights. Pick up a copy of Cracking the Code Interview - This book is the bible of coding interviews. Like this article it doesn't tell you how to cheat or shortcut your way into getting hired - it gives you a great framework to upgrade your skills. Practice questions are included and it gives you all the toolsyou need to really sharpen your skill set. Take this Course on preparing for a job interview - This gives you the information you need to really prepare yourself. This course covers:Job Interview BasicsAlgorithm Based QuestionsTypical QuestionsComputer Science QuestionsGetting Experience It really covers what you need to know to succeed in 2 1/2hours. Well worth it. Watch this video about how to prepare yourself for Developer Job Interviews - This is created by John Sonmez, who you may already know. There's no question that John is a successful developer and he's more than willing to share what has worked for him. It's well worth checking out. Exercise - OK I know this will sound silly, buthere's something that will give you an extra edge. No matter what time of day your interview is, hit the gym or do some cardio an hour or two before the interview. This will ensure:You are refreshed and energeticYou have oxygen flowing through your bloodYour muscles will be relaxedA good hard workout will make sure you are charged and ready togo for your interview. You don't want to seem tired or lethargic in your interview. You want to be at your physical and mental BEST. Preparation is everything. The more you prepare the better you'll feel on the interview day.Action: Start training like a boxer. Get fight ready.ConclusionCoding interviews can be brutal. You can take the sting off themby doing the following:Learning Sharpening your skillsPracticingThese things will ensure your success. Trust me, after working on crazy problems in LeetCode and HackerRank the whiteboard tests are so much easier. If you do this alone, you'll be successful. If you have comments feel free to share or yell at me on Twitter and we can discuss it. L O AD I N G. . . comments & more! SAN FRANCISCO (MarketWatch) -- A Chinese software firm may have replicated the popular Internet-phone software developed by eBay Inc.'s Skype unit, a development which, if true, could blunt Skype's growth in a key emerging market. Skype is aware of the claim, but so far company officials "have no evidence tosuggest that this is true," Skype spokeswoman Kat James said in an email message. EBay EBAY, -1.55% bought Skype for 2.6 billion in cash and stock in September, betting that its software, which allows users to make PC-to-PC calls for free over the Internet, would become the leading communications platform for Web consumers. Typically, onlypeople who have downloaded Skype's software onto their personal computers can call other Skype users on their PC. Yet on Thursday, the chief executive of Vozin Communications, which also makes software that allows PC users to make phone calls, wrote in his blog that a friend of his in China called his Skype account with software developed by aChinese software firm. MarketWatch wrote a story about the claim, made by Charles Paglee, on Friday, as did CNET. Paglee did not identify the software firm in question. But based on what appeared to be an Internet address shown in a screen shot posted on his blog, MarketWatch reported that it could be Hanzen Corp., a Chinese softwarecompany. On Saturday, Paglee in an email responding to MarketWatch questions, identified himself as a former chief executive of Hanzen and wrote that "Hanzen is not in any way involved in the reverse engineering of Skype." Paglee said in the email that the words "hanzen.cn" were in his screen shot because it is his Skype user name. Two requestsfor an emailed response from Hanzen, posted on the company's Web site Friday and again Monday, were not answered. Friday's version of this story incorrectly reported that MarketWatch also called the company. According to Hanzen's Web site, the company sells a suite of business applications, including products called Hanzen Office, HanzenWord, Hanzen Excel and Hanzen PowerShow, that "offer users the same functionality and compatibility with Microsoft Office at a fraction of the price" of Microsoft Corp.'s offerings. The Web site, which also states that "overseas software companies come to China and sell their products at the same prices they charge in their home country," andfurther calls such software "outrageously expensive," says the company has "a number of different software projects in the works." Released in late 2004, Skype's software has been downloaded by more than 100 million users in more than 100 countries, according to the company. Those numbers surpass the benchmarks set in the early days ofHotmail (since bought by Microsoft) and the music file-swapping sites Napster and Kazaa, making Skype among the fastest-growing user platform in Internet history. Yet for all of Skype's popularity, analysts have raised questions about how much revenue eBay will generate from Skype, which gives away its basic software and charges only for add-onfeatures such as calling cell phones from a PC. Ebay has forecast that Skype will generate about 200 million in revenue this year, thanks to a series of product upgrades and the addition of new, business-focused Skype products. If Skype's software has been replicated without its permission, Ebay would not be the first U.S. company to fall victim toChinese software pirates. Cisco Systems Inc. sued Chinese rival Huawei Technologies Co. Ltd. in January 2003, accusing the firm of reverse engineering the copyrighted code that controls Internet routers. Although Huawei admitted no wrongdoing, it agreed to stop selling products using the disputed software. A report by the Business SoftwareAlliance, a group funded in part by Microsoft, estimates that 86% of the software sold in China in 2005 was pirated, which cost global software companies 3.9 billion in lost revenue. Skype is making a push into China through a partnership with the popular Internet site run by Tom Online Inc. TOM.O, -13.02% If Skype will face a home-grown Chinesecompetitor, it could siphon off new users and reduce the company's growth there. Still, given that Skype is free, it may not suffer as much from piracy as Microsoft, for example, which charges for its products. Even if there is a knock-off version of Skype, "the software would lack the feature set and reliability of Skype," said James, the spokeswoman."No amount of reverse engineering would threaten Skype's security and integrity," she added.
