I applied through an employee referral. The process took 1 week. I interviewed at Wonder Research (New York, NY) in Dec 2019
Interview
There was first a 30 minute cultural interview. If you moved on, then you were emailed a take home test with a due date of 2 days. If the take home met their expectations, you were brought in for an onsite interview.
