There are so many companies utilizing the challenge of HackerRank to process their engineering contestants. In case you are not recognizable with HackerRank, it offers aggressive programming challenges where different developers participate by trying to program as per offered specifications. The overall submission of the contestant is graded as per to the correctness of its productivity.

Specified it is nature, there are some inherent problems in case the company relies too seriously on HackerRank for the purpose of screening. It is similar to your identical test — it exclusively tests you more on your “examination abilities” than your substantive understanding.

I just speak to a candidate regarding how he did a well more than normal challenge without really knowing data science at all.

When you will search online, you will find that there are some other articles that covering the disadvantages on using HackerRank (together with one on how to use HackerRank (and other same type of platform) can spoil your possibility of hiring a best senior developer).

That being supposed, it is explicable that why some companies will adopt that for early testing: it is quick, reasonable and can screen out different people that would not even trouble to do it.

Known that it will remain and possibly continue to develop as a way for businesses to screen for abilities, professional team has come up with a complete list of necessary things that you can perform to get ready yourself for the challenge of HackerRank:

  1. You should know that challenges are timed, confirm you are not focused and disturbed.
  2. Know that your success ratio 20–30% comes from the familiarity with the system. Earlier than you start the actual challenges of coding, try some others, like warm-up algorithms. Confirm that you know how to submit and execute your code.
  3. Know acceptable programming languages for the challenge. In case your language of selection is not easily available, you can practice another one.
  4. Generally, there are different issues to resolve in each and every challenge and it is an inaccuracy, to begin with the toughest one. A wonderful approach is to resolve issues in ascending difficulty/time order. Briefly check them first and make a decision to implementation order.
  5. Try to reduce switching time between issues after the process of implementation. You can spend somewhat extra time to confirm it is a “final” execution and not come back again to it.
  6. Each and every problem has private and public test cases. The score you will get is completely based on both. In case code execution passed all of the cases of the public test, it doesn’t mean it will pass all the cases of the private test. Think regarding edge conditions, like one element input, empty input, two elements, different elements, etc. The environment of HackeRank permits you to run the specific code on your customized tests.
  7. At least submit somewhat for each and every problem. It is very much simple to capture some important points though you don’t understand how to resolve the issue. Though, in case you do not know how to resolve all the concerns, try to make out a minimum one.
  8. Home preparation makes the distinction: some types of templates could assist as you can copy-paste them throughout the challenge. Such as DFS/BFS/Binary search.
  9. You should practice first as greatly as you can. You can try resolving the minimum one problem from every algorithmic sub-domain.
  10. A wonderful result is not a magical thing, it is sweat and practice.

Insights of Recruiter: Do you know cheating brought to further level?

We have so many candidates that are coming from recruiters. How are they evaluating contestants from other resources?

See the below image on a difficult question [Like trading algorithm dynamic programming].

Most of the candidates get 0 points: running out of time, not able to answer, incorrect algorithm, or partial/incomplete solutions (Like, wonderful start but not sufficient to pass any unit test so far).

We want to show a similar type of distribution over candidate’s pool but HackerRank does not give that graphical representation anymore.

Anyhow, we know estimated numbers. The candidate’s distribution is approximately 50/50% on each extreme. That is considerably superior to 75/17% from the normal population. We can compare that particular number with the time spent on a visual code review and the question.

The possible result is that candidates that are coming from recruiters do better, mainly on difficult exercises. Actually, it is incredible how much superior they do!

Important Lesson learned:

  • For recruiters: Keep in mind to instruct the candidate for the test as well as train him to write down possible changes.
  • For candidates: Keep in mind to ask the recruiter for support earlier than the test.
  • For businesses: Be careful high-rating candidates coming from possible recruiters! In specific, do not calibrate scoring as per on extremes scores from some cheaters.
  • Challenge: How more does it take you to resolve a trading test? [Medium difficulty, dynamic programming].

Customized Tests HackerRank

Some companies can note down customized exercises and they should. It is really very hard and it needs particular abilities but it is absolutely worthwhile.

It is just an efficient solution next to Google if carefully done. (Actually, it is surprisingly tough to make some exercises that are both easy AND not simply available with Google on more than 1000 coding forums and tutorials).

Miserably, it would not assist next to recruiters.

Conclusion

Did we just spoil pre-screening of HackerRank? Obviously not! There is an unlimited supply of bozos not able to tell the differentiation between Internet Explorer and the Internet.

If you are a candidate and want to beat the HackerRank test then you have to be proficient. You can use the facility of internet technology. There are so many websites that are able to help you and you can easily understand How to Beat the HackerRank Test With a 100% Score.

If something, this article makes HackerRank superior and more appropriate. Now a test is all about searching for assistance on Google and subtly fixing damaged snippets of unintended code written in the incorrect language.
