I recently completed my Meta interview loop and wanted to share my experience, especially because I couldn’t find much about the AI-enabled round. Hopefully this helps someone preparing.

Phone Screen

Questions: Add Strings, Top K Frequent Elements
The interviewer was really friendly and the interview went well overall.
Interestingly, when I got the feedback later, there were a few very minute picks so subtle I didn’t even realize them during the interview. Still, the conversation felt smooth and I was able to complete both questions comfortably.

Verdict: Selected for onsite.

Onsite Coding (DSA) Round

Questions: Square of a Sorted Array, Basic Calculator II

This round was honestly rough. The interviewer felt rude and kept interrupting, which threw me off. I finished the first question fully and explained my approach clearly. For the second question, I explained the whole approach correctly and wrote the complete code but made mistakes, so the final output wouldn’t have been correct. I also got a bit confused because of the interruptions. Overall, not my best round.

AI-Enabled Round

This was completely new to me, couldn’t find interviews about it anywhere, so sharing details here.

It was a string-processing question. I completed the debugging portion and also wrote the function implementation, where I had to remove words from a list if they shared common letters. Time ran out right after, so I’m not sure if there were more follow-ups.
The interviewer here was extremely friendly and helpful, which made the round feel much better.

Product Architecture Round

I was asked to design a newsfeed / Instagram-like system with posts, likes, comments, etc. I listed out the requirements, core entities and API routes and started HLD by drawing out the services and the database, and before I could finish the overall diagram, the interviewer jumped straight into follow-up questions. He didn't even seemed interested in it.
There were also a couple of UI-related questions—very random ones—that I could answer a few but couldn't for 2 of them. These didn’t feel predictable or like something you’d find in preparation guides. Overall, I am not sure how should I evaluate it. The interview seemed convinved with all of my answers and design too maybe.

Behavioural Round

I got the standard 5–6 behavioral questions with follow-ups on 2–3 of them. The interviewer didn’t feel very friendly, and I got nervous at the start—I fumbled answers for the first 2 questions. It wasn’t my strongest round, but I recovered and answered the rest of them nicely with STAR method.

I completed all my interviews 2 days ago.
Verdict: Rejected
I got no feedback.
