The interview process was3 rounds. First was screening with the recruiter. The second was with the manager. Then with multiple team members. It was all on zoom. The final interview was 90 minutes.

The interview process at EnergyHub is thorough and includes a written or presentation-based exercise, along with several rounds of interviews. Everyone I met during the process was kind, respectful, and engaged, which made the experience feel personable and relatively laid-back. That said, candidates should be prepared to invest significant time and effort, often over several weeks. Unfortunately, despite receiving positive signals along the way, I ultimately received a rejection—via email—after a prolonged period of silence and multiple follow-ups. There were two main issues that shaped my experience into something closer to neutral-negative: 1. Communication Gaps with the Recruiter. While I assume the recruiter was managing a heavy workload and came across as competent and friendly, there were too many instances where I had to chase down updates. I was repeatedly told I’d hear back by a certain date and didn’t, including after my final interview. Ultimately, I had to follow up several times and only received a formal rejection nearly three weeks later. That kind of delay—especially for a finalist candidate—felt dismissive. A timely, transparent response would have made a big difference, even if the outcome remained the same. 2. Disorganized Panel Interviews I completed a writing exercise prior to the panel interviews, but surprisingly, it was never referenced during the conversations. The interviews themselves felt loosely structured, with a wide range of questions that were sometimes redundant or mismatched to the context. Some interviewers seemed under-prepared, which made it difficult to know what to expect or how to tailor my responses. That said, I had a genuinely great conversation with the person who would have been my closest team member, which stood out as a highlight. Overall Impression EnergyHub seems like a great place to work, and I wouldn’t call the process a waste of time—just one where the investment felt disproportionate to the outcome. As with many tech companies, the competition is high, and you should be prepared for a long process that may not result in an offer, even with strong signals along the way. My advice to future candidates: go in with realistic expectations, advocate for yourself when communication stalls, and don't take a delayed rejection personally. Still, there’s room for EnergyHub to improve the candidate experience—especially at the final stages where communication and organization matter most.
