I applied last mid-November through their career site. Within 1-2 days, I received the invite for a behavioral interview through Hirevue. After completing the behavioral portion, it took 1-2 days after to send the coding challenge. In my experience, it was standard GM timing. However, I did not hear back from them until late January that they would like to move forward for the final round interview. The entire process from applying to hearing a decision was roughly 2 1/2 months. They definitely take their time selecting candidates for their roles.
