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.

Recruiter screening call, gauging interest. They were mainly interested in learning more about me, and how my expericnes may align with the role and company. Got the interview before any online assessment was shared, directly after a cold application.
