In a single day I got email from 2 recruiters from different teams.Started the process with one of the team ( As twitter has a policy that you cannot interview with 2 teams at the same time).Initial phone screen with the recruiter and then she told me a coding exercise will be sent to you which should take around 3 hours to complete. I completed the challenge in perfect time and optimized the code a lot and solved the problem completely. I was pretty sure I will make it to the next round, but after 2-3 days the recruiter sent me an email that she didnt not receive a positive feedback from the team.I was really shocked and asked for some feedback.
Recruiter was really good as she took some time to provide me feedback(which no company does).She told me review was " Problem was solved completely and outputs were correct" but the person does not have OOPS skills and knowledge.I was shocked to read this as no where in the problem was specified that I have to use OOPS concepts and had freedom to code in any language(I choose python) . I am not sure how can you judge a person on OOPS skills even when I didn't even use OOPS concepts in my code. I could have easily coded that In JAVA if they wanted me to judge on that.
Interview questions [1]
Question 1
Coding exercise of a feature that Twitter already has in production.
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
Interview
Ho effettuato un colloquio conoscitivo con HR dopodiché una sessione di live coding e domande tecniche con il responsabile dell'area. Domande vertevano su vari algoritmi e complessità in termini di tempo e spazio
