I applied online and had an introductory chat with the recruiter who then proceeded to set up an initial tech screen with the hiring manager. After the first half of a deep dive into my resume and current work, the hiring manager also did a pair programming exercise (Javascript async & promises and remove duplicates from a given list). What followed was a virtual onsite (given the COVID-19 situation) of 4 hours. These rounds were focused on data structures, algorithms and complexity optimizations with one round of a very open ended system design question to design a chat application. Most of the interviewers were helpful but were focused on solving the problem and hardly interested in getting to know your working style/body of work. One particular interviewer who happened to be my last interview, single handedly lowered the rating for my interview experience. She was outright critical of my solution, impatient and constantly wanted to dry run my partial solution with examples. The intrusion made it hard to focus.
