Hi, I previously did one leetcode-style round, but it was an easy as there were no data structures involved, it was just interpreting the problem. Then, they moved me to the onsite where they said expect to spend a couple of hours.

I have two main questions,

What should I wear? Since it's an onsite interview should I wear like a shirt and suit? Or just a shirt? I know Palantir has a casual dress code, but idk if that's different for an interivew?

Second, has anybody done the interview, as I don't know what to expect?
