Opening the technical round, I was taken aback when they asked me to implement a thread-safe LRU cache, which I had just practiced on prachub.com during my prep. We spent a lot of time discussing different locking strategies, and I had to explain how to extend the cache for TTL-based eviction. It felt quite intense, and though I received an offer, I ultimately declined as the team dynamics didn’t seem like the right fit for me. The coding question was definitely a highlight, and I'm grateful for the targeted prep I had done.

First you have to do Hackerrank, which is doable but can be tricky. Then they like to screen your coding with leetcode like problems. After that, they start screening your design skills and general technical depth.

leetcode + design, tech deep dive, very similar to the Big Tech
J'ai postulé via une agence de recrutement. Le processus a pris 2 semaines. J'ai passé un entretien chez Two Sigma (New York, NY)
Entretien
Had 3 rounds of Technical Interviews which I cleared easily. Recruiter told me that there would be few behavioral interviews once the headcount freeze would be lifted. It has been more than a year now and even after several follow-ups haven't received any response from the company. It also appears that I am not alone and there are many others who have cleared interviews but were kept on hold due to unavailability of headcount. 2S needs to stop wasting precious time of candidates if they do not intend to hire.
