Ameresco Engineering Assistant Internship interview questions

Initial contact was made by branch manager a week after submitting my resume to set-up an in-person interview. While I waited for my interview with the branch manager, the HR department emailed me background check consent forms to sign and fax back and scheduled a phone interview with me. I first had my phone interview with HR and a couple days later I met with the branch manager. Three days after my interview with the branch manager, the branch manager notified me via email that I had been selected for the internship and that HR would be sending me an official offer letter soon. A week went by before I received the offer letter (the branch manager called to inform me of the delay). It took 4-weeks for the entire process. *NOTE: HR was contacting me from HQ in MA while the branch was in Oak Brook, IL.
