I finished my interview with a Phone interview from a manager. I uploaded my resume to a talent pool, got an email immediately. Next day, I had a screen phone call interview. The following day, I was kindly rejected as a candidate.

There are two rounds of phone interviews. HR arranged them to be consecutive for me, lasting an hour and a half in total, 45 minutes each. Basically talked about resumes and personal area of interests and ask questions while talking through. Questions are pretty random and are used to test the overall background of the candidate. Not many questions are related directly to the internship position I am applying for. My suggestion would be really focus on fundamental circuit design concepts, tradeoffs, know what you are doing in every step of the design process.
