I had a phone call by a senior member of the group, 2 weeks after, get an on-site interview invitation by the hiring manager. On-site starts at 10 am, ends at around 5 pm. Totally 6 round of 1:1, including VP and manager. Most questions are technical, few are behavioral.

It was screening round. whole interview was based on single Digital Design question. He was not helping me much, when I was not able to solve, I told him about my thinking and then he helped but overall very poor. I was not prepared for it
