Plug Power interview questions

Phone Screen, followed by a recorded behavioral round (tell me about a time you struggled on a team project... ect.) Then finally, a technical round with the stack engineer and another senior level individual. Asked me to explain a lot of the technical details from projects on my resume. Seemed like they were trying to gauge my ability to explain complex topics in a simple way.

3 rounds of them. 1 with recruiter and other with hiring manager. And then the last one regarding offer negotiation. One of the most important parts were I was interviewed last by the CMO herself.
