Meta L6 Interview
Do Meta ask HARD LC problems to senior engineers? Gearing up for an onsite next week so wanted some insight. Thanks! TC- 275K
How many yrs of experience do you have ?
10+
They asked me LFU cache for a sr research engineer role, interviewer was an insecure mf.
LFU is still a popular interview question. I’m worried about a random hard question. Tough(more of impossible for me at-least)to solve in 15-20 mins.
Idk LFU is hard to solve in that time if you haven’t seen before. But yeah that’s possible. You need either to solve 2 mediums or 1 hard completely at E5.
I got LC hard in phone screen , so u never know.
Dang. Did you make it?
Unfortunately not.
My onsite for E6 is in two weeks. Recruiter told me that there is difference in coding interview for E6. The difference is in the design interview. It is more important, and you are expected to drive the conversation.
Yes, they mentioned that to me as well. But if you fail a coding interview, it’s a ‘no-hire’ at levels
Wayfair, what if you apply to another position now as you can apply to 3 positions with one referral? Will they still consider the failed coding interview or start from scratch?
Meta doesn’t really ask LC hard because they usually ask two questions per coding interview so they don’t have time. Just study the recent tagged questions on LC, Meta has a standard question bank now that is all on LC.
I got one hard out of all six coding questions (two screen, four virtual onsite).
Which hard did you get?
Something about an island and sea levels rising. Basically it’s a tree search problem wrapped in a binary search problem.
If you look at the comments on Meta-tagged LC hard questions, usually Meta asks a variation of the question that makes it more of a medium than a hard. The Hards on LC often rely on DP for optimal, but Meta explicitly does not ask DP
Meta LC is all tagged
Thanks! Yes I practiced all those tagged ones. There are a few hard ones as well which seemed pretty complex to solve during an interview. Why interviewers have to be a dick and ask hard problems to senior engineers 🤷🏻♂️🤷🏻♂️
You would be surprised how many senior people I have seen that weren't good at coding (like clearly not good). Now, this is a separate question, if you can still be successful engineer without being good at coding. At some point Meta decided, you can't (or less likely), but I believe the decision was made long ago, it is different industry and different company nowadays
