MaxLinear Communication Systems Engineer interview questions

Followed up with a recruiter for about 6 months to get the call for an internship.Had a 30 minute technical phone interview after a month after following up with the recruiter. Then had face-to-face interview after following up for 5 months.I was told that 4 people will interview me.The interview was scheduled at 1 pm. Reached about 30 mins earlier. I was asked to take a written test. This came as a surprise to me. After the written test, there was a HR call over the phone in the conference room asking general questions like my availability,eligibility to work, previous work experience etc. Then started the face to face interview. One member walked in and asked questions. After an hour he left and another member walked in and asked questions. So it was like one hour one person.
