I applied online. The process took 2 months. I interviewed at Meta (Londen, Engeland) in Sep 2024
Interview
1 round of problem solving
Interview Day:
1 round problem solving
1 round behavioural
2 rounds system design
I did so well on all rounds except the first design round. They said they wanted to redo a design round and I asked them to review the second design round as I did so well on it. They said that was a callibration round and I wasn'n in the random set of candidates where they'd use that round. So basically was an hour of my life wasted lol.
It was frustrating but I did a 3rd design round on a short notice as I had travel plans for a whole month ahead and unfortunately didn't make it.
I'd say everything else about the process was smooth and recruiters were extremely helpful
Interview questions [1]
Question 1
For problem solving I remember questions I'd categorise as leetcode mediums.
For system design I was asked:
- Design a trending topic engine for a social network
- Design Messenger
- Design LeetCode/CodeForces like system
Overall, the process took a little over two weeks, which felt a bit longer than I anticipated. After a quick screening, I went through two technical rounds focusing on coding and DSA concepts. One of the questions was a classic palindrome check; mid-way through, I realized it was something I had practiced on PracHub just days earlier. The final step was a casual behavioral interview. I was relieved to get an offer shortly after, which I happily accepted.

Question 1
Given a string, determine if it is a valid palindrome considering only alphanumeric characters and ignoring case.

Interview
It's honestly striaght from leetcode tagged
There are no surprises if you do tagged you would be good and do well.
System design is much harder. Would recommend using hello interview.

Question 1
Design Twitter and consider if it was suddenly an extremely low latency env
Grateful doesn't even begin to describe how I feel about landing this role. The interview loop was smooth and friendly. They kicked things off with a technical round where I faced a DSA question about verifying an alien dictionary. Lucky for me, the time I'd spent on PracHub paid off, as it had the same type of problem just days before. After that, I had a system design discussion and a behavioral interview. Everything felt very collaborative, and by the end, I received an offer that I was thrilled to accept.
Interview questions [1]
Question 1
Given a list of words written in an alien language and the order of letters in that language's alphabet, determine whether the words are sorted lexicographically (Verifying an Alien Dictionary). Walk through the comparison approach using a character-to-index map, the O(C) time complexity where C is total characters, and how you'd extend it to handle words with mixed-case letters or words containing characters outside the given alphabet.
