Product design: Design facebook news feed, but the interviewer asked a lot of tricky questions like how to support friends of friends visibility privacy, how to support tagging etc..

Behavioral: Standard format: handle team conflict, uncertainty, decision making, driving team through difficulties....

Preparation:

LC 476 (~400 in last 2.5 months) it's a bit more than neccessary. I think it's enough to just do top 200 Facebook tag questions
Design: hellointerview, DDIA, a bit of Alex Xu's books but I don't think it's good. I also try design a few common product / feature and time it carefully. It's also helpful if you're doing interviews with other companies, can use as practice.
Behavioral: Prepare ~20 questions, then use ChatGPT to assess and feedback my answers, then adjust the answer + take note.

Recuriter get back after 2 days and told me all rounds went well and they will submit my profile to the hiring committee as well as move to team matching.
However, I got another remote offer and already accepted that. I suspect the team matching will be very slow and could esily take months. The recruiter told me they slow down the hiring, so I don't know what happen to everyone in team matching phase. The offer will be expired after 12 months tho, that's a possibility.

Any one still in team matching phase and how long you've been? Besides, the compensation pacakge reported recently are quite bad for London. I think they're all lowball offers.

UPD: recruiter got back and told me no new headcounts for product eng role, but there are openings in enterprise eng and whether I could consider switching.
