Asked me to do HackerRank coding test for 2 hours and 4 coding questions. Although the job description said Matlab is the key coding platform, what was given by HackerRank wasn't based on Matlab (or even R). I am not a cs guy, and sensed that the test was designed largely for cs people. I did coding in Matlab and sent a separate email to the company's HR. Got rejected later. Felt that the company's job description doesn't match with the test.
