Applied online in February by emailing resume, cover letter and references directly to the company. The HR department reached out to me three months later, in May, to schedule a half-hour preliminary/HR interview call. The scheduling was extremely unprofessional. The recruiter failed to call me at the scheduled time *twice*, and I had to reach out both times to them to reschedule. We finally connected on the third scheduled call. The preliminary interview was straightforward. It was just a discussion of my qualifications and the details of the position I applied to. There were no behavioral traditional HR questions. After the prelim interview, I was advanced to an hour-long technical interview on the phone. This was another relatively straightforward conversation about my background, though in greater technical detail than before. At the end of the interview, I was asked some object-oriented programming and algorithms quiz questions. I felt that both the HR and technical interviews went well, and I was able to demonstrate my subject-matter knowledge in my answers. However the company completely ghosted me after the technical interview. I reached out twice to inquire about the next steps, express my interest and ask if I am still in consideration. I would have at least appreciated being told that they are moving on and looking at other candidates. What I got instead was complete radio silence. Overall I felt that Exa's hiring process is incredibly unprofessional and frustrating. I will not be applying for any positions with this company in the future.
