The team leader knew me from other workgroups and projects, which helped secure an interview for the position. Getting an interview inside a department you don't work for is extremely difficult even with sterling credentials. Follow up through emails to have success. I was familiar with the position but job postings list far more tasks and duties than you might expect. Interviewers narrow the focus quite a bit. It's best to ask early on what the expected tasks for the first 90 days are.
The interview was held with two leads, and took about an hour. They stated upfront 6 candidates were under consideration. Questions followed a round-robin format, and the leads took turns asking about job history, familiarity with processes and technology, and getting deeper into behavioral questions. Behavioral and situational questions took about a half hour. I felt comfortable with their style and they were warm, personable, and friendly.
About a week later, I found out another applicant in the department already doing a similar job was offered the job. They were very impressed by my interview skills and promised to keep my resume under consideration for any other openings. I'm not surprised. Systems knowledge and seniority win out at BCBSM. I'm disappointed but it's good experience.
