Samsara interview questions

ask a system design problem which is easy, the interviewer was quite good and wo discussed a lot about this problem. A few days later, HR send me email that they won't move forward with me and I don't konw why.

Met recruiter at a startup fair at my university. She reached out to set up a technical phone interview which was fairly simple - moved on to another phone screen before the onsite. The onsite was a batch onsite where there were many folks (around 50) from different unis. The batch is divided into 2 groups - a morning and an afternoon group and both groups meet to get lunch along with the CTO/CEO. It's a great time to get to chat with the leadership and talk about their challenges and projects. The company has a great vibe. After lunch, there is a product demo - where the team talks about their product and there is a panel set up to answer any questions, any prospectives may have. Three interviews follow after which they surprise you with a goodbye gift and reach out soon after.
