I applied online. The process took 2 weeks. I interviewed at X (Boston, MA)
Interview
Recruiter was very friendly and available until they gave me the code challenge. I sent that in, and no word for a week. Then a form email saying I don't match any jobs at Twitter. What a kick in the gut. I thought I did well with the code challenge, though it didn't do everything they asked it was fully test covered and resilient. And easily finishable, if I took another couple hours at it. So I was pretty shocked after all that effort that not only do they reject me, but do so with no communication except the ambiguous and all encompassing form email. Really hurt my confidence.
Interview questions [1]
Question 1
Asked to parse an ini file into Ruby objects accessible by dot notation. Take 3-4 hours.
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
