Summary
I shared my Meta E5 Infra interview experience in London, detailing phone screen, DSA, System Design, and Behavioral rounds, ultimately receiving an E4 offer.
How it went
Giving back to the community where I got all the resources from
Phone Screen
1) Diagonal Traversal of matrix (LC 498) :
Similar to LC 498, but didn't need to flip the direction of traversal for each diagonal (so easier version of leetcode question).
2) LC 408 variant.(was asked the leetcode question first and after the approach was provided, he went with the followup which was varaiant)
both word and abbr can be patterns.
Solved first question and gave approach to the follow up for second but didnt have time to finish the question.
Got selected for the onsite rounds
DSA1
1) vertical order traversal (LC 314)
2) K Closest points to origin LC 973
Solved both the questions
DSA2
1) Some max K question (classic miHeap type question, dont remmeber exactly)
2) a variant of two sum
Solved both the questions

1) Adclick aggregator
Behavioural
Dont remember the questions but the usual behavioural questions.
Got offered E4 (downlevelled) position. Team matching pending but can take time.

How they prepared
You will defintely only have 35mins no matter the round, so make sure you prepare for it that way. You need to solve both questions in the most efficient approach for onside DSA's.
DSA:
DSA questions are repeated by meta, so definitely look into meta's recently asked questions and meta tagged leetcode questions.
Special shout out to codingwithminmer. May god bless you for all the effort you are doing to help out people with your youtube channel and clearing doubts over all the meta tagged posts.
Definitely go over codingwithminmer's playlist of meta questions and variants. If you aren't doing this you are definitely not giving your 100% for your preparation.
System Design
Hello Interview.
I have taken premium , I did like the Guided Practice section of the premium. It does help in simulating kind of an interview experience and gave me pretty good confidence. Even if you dont take the premium, hello interview is still the goto.
