The interview process goes like this:
In my view, this was the worst interview experience I've ever had. You complete the assignment with production-grade coding. Then, in the assessment round, they ask stupid, useless questions, mostly because the people conducting the interview were not qualified enough. They will waste 90 minutes of your time.
Even though you explain your solution properly, after a week they informed my recruiter they do not want to proceed with the candidate. Seriously, a total waste of time.
