Illumina Software Engineer-I interview questions

I applied online (for 6 other intern positions there as well), and got a video interview (for this position only) about a month. The interview questions were fair but very brief. Got a rejection email a couple weeks later. That was the only communication.

I was applying through a recruiter for this role. First round is so called digital interview, have to sit in front a camera to answer few questions. I didn't do it quite well, as it's a bit awkward. Second round is onsite technical interview with senior developer and staff developer. They asked some questions about multithreading, design patterns etc. Questions are not very difficult and they are quite happy with my answers and experience. Third round interview is with a manager. He asked about my general background and explained about the company and this role. He seemed to have some concerns about my Science degree, as he was more looking for CS or engineering degree with more hardware experience and he also asked my GPA. Besides, he said my years of experience was not enough, as I have 4 years experience and this role requires 5 years. So I'm still waiting for their response. Guess it will be a reject.
