I applied through a professor's reference and received a call from HR. She asked basic questions about handling conflicts, multitasking, research work, etc., and scheduled a technical interview. The topic for the technical interview needed to be chosen from either control theory, embedded systems, or signal processing. I chose control theory, and the questions were all undergraduate-level, covering feedback control, eigenvalues, L'Hôpital's rule, stability, and poles in the LHP. I aced the interview. Since the interviewer did not comment on any of my answers, I couldn't gauge his knowledge.

I received a call for the next telephonic behavioral interview. A manager called me and asked about specific instances of receiving constructive feedback, what I would change in my current job to make it better, and multitasking. She delved into the details for every topic. I aced this interview as well. However, there was a follow-up interview that I messed up.

Initially, I applied for a summer internship, and the HR person mentioned they were looking for a minimum of four months. My professor stated I could only commit to three months due to my participation in a robotics challenge.

I had two options: I could have applied for a full-time position in the fall or applied for an internship in the fall. Since an internship offered more flexibility for both students and employers, I decided to go for an internship in the fall.

When I explained my situation, which was somewhat complicated, they said they would get back to me with a decision and also explained the monetary benefits of an internship. The next day, I received an email stating they did not consider me for the current openings.

The questions were not difficult at all.
