Initial HR interview via phone call. They asked your typical first interview questions: "Describe a time you had a conflict with a teammate and how you dealt with it." Use the STAR method.
Video interview with an RSM. They asked similar first job interview questions, like "Describe a time you overcame a challenge." Just be yourself. I used a personal story that happened over the weekend where my soccer team had a comeback at a tournament and ended up winning. Later, the interviewer said she really liked that personal story. Come equipped with a real workplace/school example as well, just in case.
In-person interview: They flew a group of us in. Current TSRs at TI took us out for dinner. Be yourself but watch what you say. They're not giving hiring managers the green light but they can call out some red flags if they see them. I became good friends with these people from the beginning. Highly recommend just getting to know each other.
The next day with full of interviews. This order could be reversed but in the morning, we had an interview with an Area Director to have a sales pitch of a vacation package. The key here is the ask open-ended questions first "What would be your ideal vacation?" Then you can hone in on the specifics later. Avoid Yes/No questions and playing 21 questions. Be personable and have fun with the interview.
During lunch, you're together with the TSRs again. Same situation, just get to know each other. Also, be nice to your fellow interviewers and get to know them. Not only is it fun, but the people who didn't participate in group conversation didn't get offers.
In the afternoon, you had an interview with 2 people (Regional Sales Manager and Worldwide Account Manager for me). It felt like a good cop, bad cop situation, trying to make you stress and see how you handled it. They were asking questions like before "Describe a time you overcame a challenge." Then one of the interviewers would pressure you: "I get a lot of rejection in this job. I get a lot of angry customers. Are you sure you can handle this? I had to go to my car and cry and build myself up. Are you sure you can handle this?" I responded with Yes, and described how I overcame a challenge.
Just keep your cool. Stay calm and collected and give examples of how and why you can do this job.
I got a call from the hiring manager the next day with an offer. I hear this is how it usually happens.
