Staff Software Engineer Interview Experience - United States
Process
One talk with HM. Two technical interviews on site. Got positive feedback and supposed to have one more interview with VP Puneet.
Tried to schedule a call with him several times. He didn't show up twice. Cancelled twice. And then said no need for backend staff engineer for current team but need UI staff. And want to move my application to TSE. Very unprofessional.
