Overall, I found this to be a very challenging experience. I struggled with the majority of the material and concepts presented, which made it difficult to keep up at times. Many of the problems required a deep understanding of the underlying principles and strong problem-solving skills, particularly in areas related to algorithms and data structures.
In hindsight, I would highly recommend dedicating significant time to studying LeetCode (LC) and Logic Puzzles (LP) in advance. Practicing these types of problems regularly would definitely help build the intuition and technical foundation needed to approach the questions more effectively. With better preparation and familiarity, especially in algorithmic thinking and pattern recognition, I believe the experience would be much more manageable and rewarding.
In summary, while it was a tough challenge, it also highlighted key areas for improvement and emphasized the importance of consistent practice.
The technical round hit me with a classic array manipulation problem: moving zeroes to the end without disrupting the order of non-zero elements. As I tackled it, I felt a wave of familiarity wash over me; I had just practiced a similar challenge on PracHub. The rest of the interview followed a straightforward path, with some easy behavioral questions sprinkled in. Overall, it felt very easy, but I wasn’t quite the right fit for what they needed, so I didn’t receive an offer.

Question 1
Move zeroes in an array to the end while keeping non-zero element order, in place
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.

I applied online. I interviewed at Meta (Menlo Park, CA)
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.
