Candidate, I am sorry that you had no follow up! While we cannot ensure a follow up for every applicant (although every applicant should receive an email update), I am surprised to hear that someone we went through both rounds of interview and an exercise with did not receive a personal update. Please know, if you still want feedback on the exercise you completed or want to reach out, please feel free to reach back out to us. Thanks, and good luck whichever way you decide.
