Was asked to submit assignment for a problem which took me around one week of continuous effort and then submitted it. Since then the HR has ghosted, and there has been no reply from the HR. It's been a very bad experience from HR of the company, who asks people to solve a very complicated problem and then stops replying. Completely unprofessional behaviour. This should be the first red flag to join this company. I suggest stay away from such unprofessional companies.

I applied through my college . The process happens round by round in slow pace . Second round happened a week after first round . After the results of first round were announced , a couple of days later the second round was conducted .
