Google Software Development Engineer interview questions

It was decent overall, the level of questions were honestly not that difficult for google standards, a lot of AI questions were asked and that about sums it up pretty much

Round 1: Mostly just long telephone conversations with the recruiter trying to know more about me, my experiences, my tech stack etc. Round 2: It was a video interview with a developer from Singapore. it was the most chill round of them all, I was given a JS compiler with no auto-correct or code completion capabilities. The problem was simple " Find all matches of a small string str2 in a big string str1" I showed the most naïve solution and then sequentially made it better, he wanted me to explain how it works so I had to do a little whiteboarding where I explained the whole flow of the algorithm right down to creating hashes. Then I had to explain the big o notation, and why it's linear. etc. By the time we finished the discussion almost 45 minutes were over I thought I'd get another question but that didn't happen.
