I applied online. The process took 1 week. I interviewed at X (San Francisco, CA) in Sept 2018
Interview
Twitter hires for specific role that you applied for. I was asked about my resume during phone screen. He explained a lot about his group and the role etc. and asked me a lot of questions about resume. Unfortunately that discussion itself took 35 minutes. Thats when the Interviewer remembered about the coding challenge. He also wanted to keep last 5 minutes for my questions. So that left very little time for the coding problem. The problem itself was not difficult but by the time I came up with a design, I did not have much time left for coding it. Bottom line, keep an eye on the watch and drive the interviewer towards the coding challenge if it seems that he will not do it himself.
Interview questions [1]
Question 1
Question was related to coming up with custom data structures and writing performant functions dealing with large amount of data.
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
