1) HR interview, quite general. Tell me about yourself and why did you apply for the role. 2) interview with manager- background, experience, and behavioural questions 3) case study presentation (I presented two)

I participated in an online interview with one HR representative and two managers. The interview lasted approximately 15 minutes and had a casual tone. However, it appeared that the hiring manager had little interest in interviewing me, as they did not ask any questions. Only the HR representative posed some basic questions during the interview.
