OA, followed by a 1-hr technical with an engineer, and then another 1-hr technical with an engineer for the final round. Everyone was very friendly and the process was smooth, however, despite doing really well in my opinion, I didn't receive an offer. Must have been a competitive applicant pool.

Entrevista
After Professor Luis von Ahn (co-founder) passed my name to the CTO, I waited a week to hear back. I eventually wrote a follow-up email.
Before even talking to me on the phone, the CTO screened me by sending a coding task to do. I submitted it two days later and simply received a "it was good knowing you, but sorry we can't offer you a position" a few hours later.
Not sure how well they got to "know" me through a coding assignment, because I definitely didn't get to know them.
