Frontier Strategy & Growth Analyst interview questions

Applied online, had the initial phone interview with an analyst and it was very conversational and covered basic questions about my background and knowledge of the company, then had a second video interview with another analyst and was given little direction and was recorded while asked to take a personality quiz that took a little over an hour. After that, I received a rejection email a few days later from another analyst who I had not interviewed with. Overall, the process seemed unorganized and the people interviewing were new to their role/new grads and not prepared to interview candidates.

1st interview with the recruiter. 2nd interview with an analyst joined 2 months ago, who is the same role. Each interview is a 30 minutes phone interview. Most of the questions are asking about my background.
