Qualcomm Physical Design Engineer interview questions

I had applied online. The HR scheduled the interview. 1 phone screen for an hour with technical and resume based questions. after 5 days I got onsite interview invitation. 2 technical rounds and lunch with team members and finally a panel interview with 3 team leads. They were shooting questions but they were very friendly. I received a verbal offer 2 days after and was told to wait for 2 weeks for offer letter and after 3 weeks the HR says she doesn't know how long it takes to approve the offer. I am very disappointed. I don't if I have to have hopes still or forget this offer. As they gave a verbal offer I stopped applying for other jobs and was waiting for the joining date. I don't have any other offer in hand and I am shattered. I am very disappointed by the hiring process of a giant company like Qualcomm.

Was very straight forward. easy rounds. Static Timing Analysis, Timing Closure. Synthesis, Clock Tree Synthesis, Floor planning, Place and Route, RTL and netlist synthesis. Questions based on projects, PERL, Clock Tree Distribution, Power and Ground area, Die area
