I applied through college or university. The process took 1 day. I interviewed at Microsoft
Interview
I signed up for an interview through my school's career process. They asked basic hardware questions on gates, transistor, logic, op amps and filters.
Interview questions [1]
Question 1
The questions were pretty standard ie: what is the voltage in this transistor circuit? Turn a NAND gate into an inverter. and determine a filter is high pass or low pass.
Not too technical, only a few simple oral questions about coding skills. Other questions are behavioral, such as asking what's your biggest challenge so far or what is your strength/weakness.
I was directly invited to the final round. Three sessions followed, each lasting 45 minutes, with a 15-minute break between them. It was a rigorous process but an exciting experience overall.
Took about month to hear from them. Email described that your papers have been read and your interview is being scheduled. Next week the recruiter invites to a meeting the next day. 1st meeting with the recruiting manager. Sadly not invited to proceed. I was asked during the interviewing about skills that I did not have.
