Christie Digital Software Developer interview questions

Phone interview - some personality questions and short coding question to write the program for rock scissor paper game in c++. Also questions about the experience with image processing and computer vision.

Was contacted by hr to schedule a 30 minute call with hiring manager who decded to not show up but instead 2 other people came. Had a basic discussion about the job and some game design related question I felt i had underperformed and decided to move on,but was contacted by HR for onsite At onsite was presented with standard design tic tac toe question.Although i was able to write the basic crux the barrage of questions from the panel made me nervous and lose track. After that was told by hiring manager(who was present in panel) we are stopping the interivew.Thank you for your time. Overall,i gained some experience. BTW when some other employee heard that I was meeting the hiring manager,his response "Best of luck with that guy you're going to need it". Not sure what to make of it but it seems the HM had a reputation which was a huge red flag
