It was one of the worst interview experiences I've had. They asked me to submit the assignment, which I did even before the deadline, and they ghosted me. It was not just me; one of my friends also had the same experience. If you look at their GitHub repository's PRs, you will find that most of them are not reviewed. It seems they are posting fake jobs every 2-3 months just to stay relevant in the market.

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.
