Also if its an initial testing I would expect that it does not require much time investment from my part, after all how much time did the company invested in me (I presume 1-2 sec that required them to send me an invitation email)?Also its easily possible that those tough questions will yield false positive and false negative results and you can only verify this on the follow-up interview.Also these kind of tests will never indicate who you should hire, they can only indicate who you should not hire and by providing some tough questions I feel that these tests are then failing at their task.Last I believe it was very rude that they did not give you your score!

Passing Score allows you to set a score that a candidate should achieve in order to be moved to the next stage of recruitment. By my intuition you should write main algorithm body first. Recall (learn) how to use hash tables and hash functions properly.

I ... To pass these test you need to study Codility itself - it has virtually nothing to do with development.

Site Map James Cutajar is a software developer with an interest in scalable, high-performance computing, and distributed algorithms. Well, anyway, this is just my humble opinion. Auxiliary elements: Can you add some new element to your problem to get closer to a solution?

After adding test cases you can simply click "run" - it will run your function on default tests and your tests too.

And even though I guess I already had some good practice with them, I managed to do badly in stupid ways – ways that 2 years ago I had already thought about and even taken notes on.

Test it against the sample input/output. We use optional third-party analytics cookies to understand how you use so we can build better products.
