The process was somewhat straightforward, not hard, team manager was very pleasant. There were questions about concepts of CS and the technologies used in the team. I wasn't expected to do any hard leetcode.

As a freshman student with several years of commercial experience, I have applied for a summer internship at Solarwinds. We have scheduled a phone call with an HR. It went fine; the usual questions. After that, I've been asked to send a written description of several projects I've been working on. My role, how it went, what I've learned and stuff like that. Then an onsite interview with 2 developers from the team that was hiring, and a different HR who was looking to fill a different position. We have started with my past experience. Then some tech questions. It was supposed to take 1 hour, but the conversation went well and we lost track of time a bit. When it was noticed the interviewer briefly went through several C# specific questions and the interview was over. In about 2-3 weeks I've received an offer.
