EnergyHub interview questions

Firstly I got email from one of the team member about they are interesting about me. Then they polite ask me when it is good time for me to talk I like how they responding and getting interview fast. In addition I have been spoken with nice person.

I enjoyed the process at EnergyHub! I started with a phone call with an EnergyHub recruiter who had a couple of technical screener questions (mostly simple Unix commands and describing basic data structures, nothing to fret about) and then he gave me a good primer on the company and industry. Then I had a 45 min interview with 2 engineers where they asked me questions about technical problems I had solved at previous jobs. There was a focus on handling issues in production and how I had tested features I built. Following that, I had a take home which took about 2 hours and was nicely related to the work I'd expect to do at EnergyHub. Following that, I had 3 more 45 min technical interviews in the final round which all built off of the take home (i.e. imagine expanding the problem in this way...how would you adapt your code to adjust for that change?). About 30 min of the technical interviews were devoted to extending the takehome, and then 10 min were left to ask me one behavioral question. Any leftover time was for me to ask questions of my interviewers. My last interview was a 30 min conversation with the president where we got to discuss how EnergyHub fits into the current DER landscape.
