I've interviewed with many large companies and generally had negative experiences. Facebook was different, in a very positive way. It's clear that significant thought and care have gone into their recruiting process.

I noticed they were hiring front-end engineers in Seattle and applied on a whim, mostly forgetting about it afterward. A couple of months later, a recruiter reached out, and we had an initial phone conversation. This was a preliminary screen, largely non-technical, except for a few quick and simple JavaScript pop-quiz questions at the end (e.g., == vs ===, describing event delegation).

Next was a technical phone screen. This was fast-paced, with the interviewer aiming to cover as much as possible in the limited time, while still leaving room for my questions. They did a great job of keeping things moving and on track. The interviewer asked general questions about my background, followed by simple coding exercises to assess my knowledge of HTML and CSS, and the implications of different design choices. Finally, there was a straightforward JavaScript tree problem.

Next came the in-person interviews. This is where I felt they excelled compared to other companies. The entire process was highly transparent, and I received ample information and resources beforehand, so I knew exactly what to expect. It consisted of:

• Two coding (ninja) interviews
• One design (pirate) interview
• One behavioral (jedi) interview

Each interview was approximately 45 minutes long. Between interviews, a lunch was scheduled with another engineer who was not involved in the feedback loop. This provided many opportunities to ask questions about the company and culture, and to get a tour of the office.

Overall, the questions seemed highly relevant to the position. The interviewers were also exceptionally friendly and helpful throughout the process, appearing genuinely invested in your success. There were no overbearing egos trying to assert their superiority or trick me with irrelevant questions (I've been asked physics questions for front-end roles before, unfortunately).

A great experience.
