I applied online. I interviewed at Facebook

Interview

Too hard and tedious Very selective of its candidates A lot of time to prepare for the interview especially since they are algorithmic questions, they focus on that with system design too if you're already an experienced software engineer

Interview

It was a fantastic interview process. Two interviewers were assigned and both asked me two programming questions. Mostly the programming questions are coding and design and it went really great. But there certainly were better applicants with better skills than I.

Interview Questions
  • What I am very strong in technically and coding on data structures.

I was directly assigned for a coding interview. Unfortunately, the interviewer did not care very much, he was eating during the interview and did not show his face on the camera. This was very discouraging.

Interview Questions
  • Some classic dynamic programming problem.

Technicals and then more technicals. You know, they ask technical questions in one stage and then the onsite takes all day. Typical Silicon Valley company stuff. Was a "virtual on-site" due to COVID.

I applied through a recruiter. I interviewed at Facebook

Interview

It was straightforward, recruiter call first, then they schedule ahead with a video screening. Keep in mind the booked interview time slot IS NOT FINAL as it changed quietly for another day another time than the original one from the notification email. Thank god I checked it. The interviewer presented the question but she is very quiet and she frowns a lot when she saw my solution, which I consider to be quiet disrespectful. I am not good enough and prepared enough for the interview so I didn't pass that too.

The process took 4 weeks. I interviewed at Facebook

Interview

I am very disappointed with this entire process. My interviewer was unable to understand my solution to her problem and was unable or unwilling to listen. I tested my code directly afterwards to make sure I wasn’t mistaken. Sadly I wasn’t able to explain my code at all or even finish writing it during the interview. Right away I was confronted with “this is wrong. I’ve interviewed many people and this is wrong.” This was minutes into starting. All I showed her at that point in time was how I was going to reduce time complexity. I’m just upset with how rude she was. I hope this is not the standard for Facebook. I haven’t even heard back from the recruiter yet after that.

Interview Questions

  • Given an array of numbers and a key, return a list of lists for the different combinations that equal the given key

Interview

Internal transfer. Two coding and one system design. Both coding rounds have hard questions and seem to expect me to come up with optimal solution. Didn’t come up with optimal solution and failed the interview
