15 minutes phone interview, 1 round of tech interview, final round tech + behavioral; The whole process toke more than 4 weeks; HR gave feedback after rejection letter, which is very nice.
I applied online. I interviewed at Slalom Build (Boston, MA) in Mar 2021
Interview
One screening interview, one technical interview, and one behavioral interview. Overall everybody I spoke too was friendly and knowledgeable. The technical questions were more like "how well do you know this" rather than specific problems to solve.
