Spectrum interview questions

The interview process was pretty straight forward. I applied for the job through the companies website. About a week later I was contacted by an HR rep to schedule an interview with one of the Supervisors on the team. The questions asked in the interview were STAR type questions. Ex: tell me about a time in which you had a conflict with an employee and how did you resolve. The same day of the interview I was asked to provide references. I received an email from HR within a week advising that I was asked back for a second round interview to meet with the Hiring Managers. During this interview they basically asked the same type questions from the previous interview. Within two weeks, HR emailed me and advised that they would like to extend an offer. All of my communications from HR were emailed based.
