I did an online coding test sent form Palantir after my applying. It's a programming problem and it's very difficult, I didn't pass all the test cases, but I past majority of them. The next day, an hr contact me and want to give me a hr talking interview. We chat on the phone, and asked me a lot of behavior questions. I answered not very fluently. And that hr told me will send my resume to the teams, they will see if there is good fit. And after two days, I got a thank you letter.
