I had an excellent interview experience with Mixpanel. Great coordination on the part of recruiting! Mixpanel is currently building their HR department and has used a well experienced and imbedded HR consultant who has put in place many HR processes and has helped the company create a robust hiring plan for the department. Not many start-ups invest in their people as much as Mixpanel has at this stage. HR departments are critical for company success and understaffing this function is an approach that many start-ups unfortunately take. Luckily these people know what they are doing! Based on what I have learned about the company through my own research and through the team I interviewed with, this company is doing well and will scale successfully as it continues rapid growth. Also, the team I interviewed with in legal, finance, ops, customer support are great people with extensive experience. Awesome culture!
