The journey begins with a standard recruiter phone screen to assess your background, portfolio, and initial fit. Following a successful screen, you will be required to complete a series of rigorous aptitude tests. Candidates consistently report taking at least five separate tests, with a heavy emphasis on math, logical reasoning, and programmatic problem-solving.
