I applied through a recruiter. The process took 6 months. I interviewed at Firmenich (Princeton, NJ) in Mar 2017
Interview
Extremely unprofessional and disorganized. Took ages to schedule interviews and resorted to radio silence in between interviews with no feedback or communication until I pushed them to respond since I had other leads. Couple rounds of interviews went very well and they seemed really impressed and even confirmed that via email correspondence. However, they took so long to get back to me after my final round that I accepted another offer in the meantime. I would suggest being wary of working here as they appear very dysfunctional.
I applied through a recruiter. The process took 7 weeks. I interviewed at Firmenich (Tampa, FL) in Feb 2015
Interview
All four interviews were over the phone with each interview occurring with a higher tiered manager. The interview process was fair, timely, and professional. The questions were straightforward and geared to identifying the candidate's motivation. There were no trick questions.
