The process started off with an automated video screen where there are 5 predetermined behavioral questions where you submit a video response that will last about 30 seconds. After successfully gliding through it I got a hackerrank challenge that has 4 sections and we are supposed to choose two languages and they suggest you choose MATLAB/Python and JAVA/C. You have to solve close to 20 questions in which two or three involve writing a code and the other are multiple choice questions. The total time allowed is 60 minutes. After two weeks and no response, I emailed them asking if there is another round! They immediately arranged a phone screen with live hackerrank interface! The interviewer on phone screen is quite transactional! But he straight up said that he won't be giving me any feedback then and there. He asked me an array of questions spanning Signal Processing, Probability, Calculus etc.
