I applied online through the twitters job site. Recruiter reached out to me and we had a fantastic conversation. We set up a technical phone interview for couple of days later.
This is where things started to get bad. First of all, interviewer had a very cocky and unimpressed attitude. When talking about one of my projects he had a lot of condescending questions. Secondly, he refused to indicate what solution he wanted to get out of the questions he asked. You know how they say "Interviewers want you to succeed."? That certainly did not feel true going through this call. And thirdly, please don't use speaker phone and sit meters away from it. An interview isn't going well when I have to keep asking you to repeat your question.
I am glad however that I had this experience. It's always nice to weed out potential team members who you know you wouldn't get along with (I am sure in his own way he felt the same). I like teammates who are smart yet stay humble.
Don't be condescending to your candidates. You are coming in with all the context and existing knowledge possible to your interview question. The candidate does not have that luxury.

Phone screen, followed by two coding rounds, one system design, and one HM/behavioral round. Prepare with LeetCode tagged questions related to data structures, algorithms, and system design topics. Prepare for Behavioural in STAR method.
Went through two screenings and virtual onsite. Technical team members were friendly and great to speak with. Recruiters were pretty awful - the one that set up the virtual onsite gave everybody different zoom links and trying to find the correct room to join really cut into my interview time and made me stressed out during the VO. Main recruiter scheduled a phone call to discuss results after the VO for when it was past midnight in my timezone but never called or responded to my followup.
To the recruiter: you don't need to try to keep me warm by scheduling a phone call and ghosting me when I only asked you whats the decision timeline. If its rejection just email to let me know instead of wasting more of my time especially when its late in my timezone.
In general this would've been a positive experience if the recruiters weren't so bad.
I applied through an employee referral. The process took 2 weeks. I interviewed at X (London, England) in Apr 2025
