Official career page describes the role only; the fetched copy did not state the assessment process. Search snippets attribute to a Yerevan job posting an online test on statistics, probability, linear algebra, analysis and algorithms followed by 4-5 interviews, but that posting could not be fetched (removed). Glassdoor reports were blocked (403). Process is heavily research/ML weighted compared with trading-led firms.
