Had an interview with an HR person in March, successfully got to the next round with a manager. Interview was postponed, and ultimately cancelled due to COVID. HR was extremely unprofessional and didn't get back to me until May. They said I could restart the recruiting process when hiring started again. Don't recommend MS, if HR is any indicator the New York/ Boston offices are a mess.

A phone call followed by an in person interview at the office they'd just opened in Birmingham, AL including a math test and Skype call with their office in Spain
