I applied through an employee referral. The process took 4 weeks. I interviewed at Teneo (New York, NY) in Sep 2018
Interview
One brief introduction meeting followed by a full day of interviews with senior management. Company invited me to meet with CEO the following week, then didn't actually schedule a meeting and went radio silent until I followed up later.
Company has since claimed to have professionalized the hiring process.
Interview questions [1]
Question 1
Interviews were very informal "fit" interviews that spanned broad topics in the department, no specific questions or cases were asked.
