Photon UI/User Experience Creative Lead interview questions

I had Two Rounds of Interview with Photon and got selected. I was contacted by employer first, describing the opportunity and the interview requirements & Process.

Technical Round by Interviewer - Phone 5. HR Round - on Compensation, Joining date, etc 6. Confirmation by HR on Joining
