Initial call with recruiter followed by hiring manager . And then a take home assignment . Never got a call for many days after submitting the take home . This is similar to the other experiences posted here. Finally got a call back saying that the hiring managers were too busy to review and that I should hear back in another week ! I am yet to hear anything back after that from them . This was the most unprofessional experience I ever had . If the hiring managers are so busy do they think that I don't have anything else to do ? This was at Livongo in Mountain View.
