HR asks couple of questions about your personality, if you answer some arrogant answers, you will get red flag and they will not call you back no matter what your technical skills are. As some employees feedback here, tell them when NextJump will be next Google, how can you help them to do that. They like to hear those sentences. You need to make HR or person who interviews you feel so great, be very positive then you will get the job. Your technical skills are not that important to get the job because HR people are inexperienced and they're driven by their emotions. Multiple choice and simulation test were the hardest one and I knew that I failed, however I got the job cause I suggested them that I could help NextJump to be next Google, it was piece of cake.
