CEG Solutions Energy Development Associate interview questions

The interviewers were very uninterested in getting to know me and only asked technical questions that are already on my resume. They also did not talk about the position at all or who they were and what they did in the company. I had to ask about the position at the very end. Completely unwelcoming.

I had two phone calls with different people from the company and was then invited to visit their office for a full day of interviews. 8 hours, 7 interviews, 15 people. The day was going great until I got to the last round, which was 1:1 with their president. He gave me a bizarre technical interview where he refused to answer any questions and didn't seem interested in understanding how I think or solve problems. As an example, I was trying to calculate how much money the building we were in spent on lighting in a year. I asked how many floors the building had, and his response was, "I don't know, you took the elevator didn't you? You tell me." It was the total opposite of every problem-solving style technical interview I've ever had, and left a very bad taste in my mouth. Towards the end of our meeting he told me that I wasn't a particularly strong candidate, that my technical skills weren't up to par, and that my writing was so-so. This was extremely frustrating to hear after I'd been in their office for 8 hours and was pretty exhausted and worn down. Unclear as to why they brought me into the third and final round of interviews if I wasn't a strong candidate. After two phone calls, 8 hours of in-person interviews, and having met nearly every person that works for the company, I didn't receive so much as an e-mail to tell me I didn't get the position. Not even having the courtesy to send me a follow-up email after the in-person day is what assured me that this would not be a good company to work for.
