Interstate Batteries interview questions

The process is lengthy yet thorough. I did a telephone interview with a recruiter who was very informative and gave a wonderful overview of the company, culture, and values. I was given a call to come in an interview with a Sr. Executive, which went really well. Though I wasn't given a call back on that role, the recruiter kept me on her radar. 2 weeks later, the recruiter called about another role, so I came in and interviewed with 2 of the Sr. Executives and it was great and I took away alot and knew exactly what they needed. 2 weeks after that, I was emailed to come back for a lunch interview, again very thorough, this time, it was more relaxed which helps when getting to know people better. 2 weeks from that lunch interview, came back and interviewed with 2 other employees that worked in the division, and that interview I received alot more insight as to the needs and the work style of the executives. 2 weeks from that point, I received the call that I got the role! I am happy that they don't make rushed decisions and I am happy I stuck it out with the interviews and processes

Very unprofessional as I assume the phone call I got from a company talent group member was the interview. I was not asked if it was good time talk/interview nor did I receive an email indicating the interview would be via phone. Very few questions were asked and they clearly didn't know I was a former employee recently let go due to job eliminations. I received a "thanks but no thanks" email after the fact.
