I had three rounds and got an offer in the end, but it sucked because there was no team to match me. So I ended up not being able to do the internship and had to find another firm.

Two LeetCode mediums and one hard. There is a follow-up if you solve the basic question. They were very nice when I asked for hints and guided me through the parts I couldn't understand.

Very long and time-consuming, but they updated you throughout the entire process, which was nice. However, three months is just too long; there needs to be a better option.
