The interview process was quick, overall it took less than 3 weeks. There were five rounds of interviews: - Phone interview - Knack games - Google type of questions, e.g. 'estimate the number of hair salons in London', 'how many golf balls can be fitted in a plane; in general, they're interested in how you think and how you and what is your logic behind it; - Meet the team - you get to meet a couple of people from the team and get an idea of the work environment - Meet the founders - general chat about why you want to work there, what are your goals Be aware that this is essentially a customer service job. You spent 70% of your time on the phone and the rest of the time on emails or chat. I felt like neither the job description or the interview made this clear. Ignore the fluffy startup language. It is a stressful environment, and your performance is continuously measured against a target. If you're comfortable with this and ready to wait for 6-10 months to expand your responsibilities, there is no better place to learn about renewable energy.

The in-person interview began with some general questions about my background and interest in the company, followed by some consulting-style problem solving questions, and finally a Q&A with current employees.
