That’s significantly better than the 75/17% from the general population. ( Log Out /  This book is the gold standard when it comes to data structures and algorithms questions. The first result is the question, the second result is the solution. For example, Practice first as much as you can. It is the only effective solution against Google, if done carefully. If anything, this article makes HackerRank better and more relevant. 99% of programmer jobs are “implement business functionality” and not “design perfect algorithm”. , Mike, your last comment is the best… become a bus driver jjaaja. In fact they are designed to be misguid you. Then you start your test and you learn that you have 90 for 3 tasks… That being said, it is understandable that why companies would adopt that for initial testing: it’s fast, least costly and can screen out people who wouldn’t even bother to do it. Sorry but all of that complaints are valid against HackerRank. What about algorithms? I am going to be looking for a job in May 2018 as my current company has been sold and I am dreading it since, like other people, I often blow the tests because of the stress and time pressure. Also there are boundary cases. I had 24 hours to do it so I could take my time. You could try solving at least one problem from every. It’s hard and it requires particular skills but it is definitely worthwhile. The majority of the multiple choice questions can be solved by an appropriate Google search. Not to mention that the HackerRank website disables copy/paste in the description area. As a consequence, the tech industry is pushing for longer, harder and evermore extreme screening. Basically there are problems with (hidden) test cases and meeting the performance expectations. It’s up to them to make something reasonable. Home preparation makes the difference: some templates might help as you could copy-paste them during the challenge. Pre-screening is fine, but there are better ways to do it like custom homework problems to code. See https://thehftguy.com/2016/07/20/hackerrank-a-glimpse-at-the-company-side/. In my current job (of over 3.5 years) get they gave me a “homework assignment” – designing and writing a fairly complex class structure and using it in a WPF app via MVVM. It’s really the company that makes the test and decides on the rating. Instead of giving problems involving bit manipulation, graphs, trees, heaps, God knows what, give a simplified version of a problem that the candidate would REALLY face in the day to day work. Let top companies recruit the top talent. The submission of the participants are graded according to the accuracy of its output. A title uniquely identifies a question on HackerRank. I think “full-screen” means full-screen on *one* display. Think about edge situations, e.g. good start but not enough to pass any unit test yet). i just hate these tests (in general, not just HackerRank) with a passion – most of them are not realistic as you get so little time to do them, you are already nervous because it’s an interview and then the questions are invariably mostly irrelevant to everyday coding or development problems. Believe me - I have taken it, and passed it, and it is as challenging as they come. Some points why I do not think HackerRank/Codility adds any value introducing more noise instead: A HackerRank assessment can take up to 60-90 minutes so make sure you’re in a quiet environment where you have enough time to practice and take the assessment. Agree with better. They might be looking for something specific in an applicant, but generally passing the test cases is … ( Log Out /  It is a programming competition, so it is kind of expected. 2. Perfect for being indexed by Google. Keep in mind that the majority of candidates will not complete a test to print numbers from 1 to 10. Now the question is are you really looking for a competitive programming champion who can solve the awkward algorithmic problem in O(n) in 30 minutes reading from STDIN? Understand allowed programming languages for the test. Do not agree with more. (Special kudos to the guys who are able to solve a problem -with a perfectly optimized solution- in less time than it would take to actually read it =D). Is that what is really needed in the job? We can correlate that number with the time spent on the question and a visual code review. Searching for a 10 lines long paragraph in Google is not an acceptable option. It’s the company who decides on the duration, the questions, the unit tests and the input (stdin or not). ), give much better insight into candidate (e.g. (Excluding the first batch of candidates who will be sacrificed as scouts). Now, *that’s* the way to do it IMHO. Post was not sent - check your email addresses! HackerRank is like your standardized test — it tests you more on your “examination skills” than your substantive knowledge. This is unfortunate, but from a hiring standpoint, I would rather risk to miss hiring an excellent engineer, than risk to hire a bad coworker. Custom HackerRank Tests. The test needed to be completed in 75 minutes. Of course not! Challenge: How long does it take you to solve a trading challenge? How Plagiarism Detection Works at HackerRank. It’s introducing automated programming tests to be done by the candidate before he’s allowed to talk to anyone in the company. This you can find on your profile page. However, if you don’t know how to solve all the problems, try to figure out at least one.
