Snowflake Project Manager interview questions

Very frustrating and unprofessional recruiting process... I firstly met 2 members from the hiring team who are very nice and approachable. Then I was asked to prepare a presentation and schedule a panel interview with additional members from the team. Every other day, I received emails from the recruiter constantly adding additional rounds of interviews (besides the panel presentation) and changing time slots. After committing so much personal time preparing for the presentation and adjusting my availability so many times, I received an email from the hiring manager whom I never met saying they chose to move forward with another candidate one day before the scheduled interview. And I had to reach out to the recruiter to confirm and cancel the interviews. Do not waste your time with them because they don't respect their candidate at all...
