I applied online and got Hackerrank assessment, It was 5 questions within 75 minutes. 5 questions with one MCQ and in 4 different programming languages. It was still fine but after 15 minutes the IDE started creating error, Like I was typing on one line and modifications were made on different lines, mostly above the one I'm typing at. I waited for some time in case it will be resolved but no luck even after 10 minutes, So i recorded the error on my phone, closed the window( which automatically submitted my test ) and mailed it to hackerrank as well as mozilla. Hacker rank replied after 3 days that we can see your test is submitted and belived the error was resolved ( I explicitly mentioned automated in the email i sent to them, again I replied that No, it was not resolved and it was an automatic submission, the error persisted as long as I tried. It has been more than 10 days but i havent heard anything back, neither from hackerRank nor mozilla. It was an extremely bad experience and it felt like the companies are least bothered with candidates. I did not expect this from Mozilla at least.

It was not that much good or bad. The interview hiring process took too much long. After applying for role it took a month to get response for next stage interview.
