Brightmark Energy interview questions

Had 5 video interviews with the hiring manager, leads from other departments, and an executive over 5-6 weeks. All interviews seemed positive and the company is growing quickly. Only reason I'm listing as a negative experience is the company did not respond to follow up or provide notice of no offer. Fairly unprofessional after 5 interviews in my opinion.

The interview was held in two rounds on same day half an hour each. First interview was with Controller and it was based more on situational and past experience experience. Second round was with VP of Accounting and it was also situational
