Second Order Effects interview questions

I had three interviews, the first one was with HR and that started pretty simple just asking why this company, hardest engineering challenging, tell me about yourself, and in the last 20-30 min she hit with some relatively basic EE questions, such as how to design a flashlight, SPI vs I2C, etc. Then I had my technical interview which was just going deeper into my resume and signal processing question, and then i had my last technical but that one was really chill just talking about what i was interested in and more questions about my resume. In the end they said they werent able to do the fall internship due to internal company stuff and my friend who was also interviewing got the same rejection email at the same time and day as me.

Had some fairly basic questions on Electrical Engineering concepts, then some more challenging ones based on managing requirements and client communication. Interviewers were friendly, and there were two technical rounds.
