I applied through an employee referral. The process took 1 day. I interviewed at Affect Mental Health (Cambridge, MA) in Sept 2018
Interview
Long, whole day process with orientation and personal interviews with founder. Founder will sneak in at the last moment that the position is unpaid.
Many others have had the experience of multiple visits to get interview or getting left cold.
Interview questions [1]
Question 1
