Met with four different engineers over a four-hour period and felt relatively relaxed. The interviewers asked questions related to the Software Engineering position I was interested in (Growth team) and I was drilled on basic JS concepts and given front-end programming logistical questions. One interviewer asked me behavioral questions pertaining to what I expected at WHOOP and how I would be a good culture fit, and another one asked relatively average programming problems you'd see on LeetCode (easy/medium). Overall I felt pretty comfortable talking with the interviewers and became convinced that I wanted to work here after learning more about their startup culture and their product.

Interview process consisted of one behavioral and one technical as the final round. The behavioral was very chill with standard questions going through resume, how you work on a team, problems you approached to solve, etc. (I did not get to the technical however)
