The stupidest interview I ever had. I had to write a review because I cannot contain my anger. I was pointed to hackerank; when I decided to do it, as soon as I saw the algorithm question I was extremely happy. Why? Because I had studied it in the past in school, I had used it recently and I was very familiar with it. I knew three solutions to the problem, I opened up my terminal to write the code and had a solution pretty quickly, but that wasn't the most performant. 0(n^2). I then I decided to improve the performance with the better solution. I submitted with confidence and had plenty of time left. I quickly received an email stating that I did not had the proper score. I was shocked since all the tests passed both locally and on hackerank, most importantly i knew this algorithm like the back of my hand!! I insisted to point out my error. Guess what i was told? and I'm copying verbatim: "Thank you for your email. The tests do pass, however, it appears that there were similarities between your submission and other submissions that the database has gathered from other engineers who attempted the test. " You have no idea how mad it made me given that it was 100% my code. The assumption there was that I cheated from one of their engineers. The fact that they made me waste my time to come to such an inaccurate conclusion is ridiculous. Instead of asking the algorithm questions face to face and put a human touch to their process they rely on a bad algorithm in their database to catch cheaters. It just so happened I was not one, just someone who studied algorithm extensively. Seriously!!?
