I received an email from the recruiter asking for my availability for an initial discussion. After I sent few available slots, the interview was scheduled. The first interview with the recruiter went on well. It was general discussion, about company history etc. Later another interview was scheduled with a manager. I was asked to work on a take home design exercise, which appeared to be related to their work. After I spent 1 week and shared the assignment, there was no response. Totally weird experience. Looks like it's a freelance work for free.
