First, there is an "optional" coding assessment based on company's interest in candidate. It's up to Eversight whether or not they want a candidate to take the assessment.
The assessment is followed by a 1 hour technical interview with the CTO, which includes a smaller/simpler technical problem than the onsite sessions.
Finally, a virtual on-site consisting of four 45-minute technical interviews with varying members of the company. Each session came with it's own technical problem or problems to solve.
