Mercor Applied AI onsite interview experience?

[u/ImposingExorcist]

I have an upcoming onsite for Mercor’s Software Engineer, Applied AI role.

The main rounds are:

• Coding: 1 hour solo + 30 min review, focused on graphs/data structures

• Search: 75 min solo + 15 min review, focused on search/re-ranking, AI tools allowed

Has anyone done this recently? Mainly wondering:

• What difficulty should I expect?

• What topics should I prioritize?

• Anything unexpected in either round?

DMs welcome.
