Was contacted by the recruiter and he sent me a test assignment. The assignment had some images based upon which I had to code and they were so unclear and just not visible. I contacted the recruiter for some better images and never heard from him back. This was very unprofessional by the recruiter.

finish online assignment first, and after about 2 weeks, their recruiter emails me for the followup, recruiter phone screen(basic question) onsite is meeting with the whole team(4 ppl at that time). 30mins per person, questions from different aspects. 45min whiteboarding, 3-hour coding, 30min presentation.
