One on One interview with a research team manager. He probes probability questions. Mostly conditional. Atmosphere quite relaxed. It was great fun. Id do it again. Every time it was cool.
Ho presentato la mia candidatura online. La procedura ha richiesto 2 settimane. Ho sostenuto un colloquio presso GSA Capital (Londra, Inghilterra) nel mese di apr 2026
Colloquio
Did an online assessment, it consisted of mix of probability braintreasers,logical puzzles, machine learning, linear algebra and programming ( mostly sorts and data structures) questions . Was not invited to the next round

Colloquio
Received Hackerrank OA for first screening. 40 minutes for 25 questions in many topics. Either "multiple choice" or "insert numerical answer" types of questions. The time allocation is very punishing, and I did not make it past their filter.
Domande di colloquio [1]
Domanda 1
Basic probability (conditional; Bayes theorem; correlation; expected value of order statistics; IID sequences), statistics (linear regression, think how beta varies under changes in the data), brainteasers (inference for ordered information; e.g. five people arrive to a place, incomplete information on arrival times and order, which option is necessarily true (or false)), speed of algorithms and data structure data access (sort, indexing; how fast does a structure access data), linear algebra (matrices, matrix operations; determinants and their properties), zeroes or maximums of curves under domain constraints (also in higher dimensions), mathematical series (where does a given Taylor series converge).
