Thank you for taking the time to post about your interview experience. We are sorry to hear you found your 3rd interview confusing and that you felt interrupted (often with 30 min phone screens our hiring managers set the expectation that they will be interrupting the candidate to cover a variety of questions). We do our best to make sure we are aligned on job descriptions and roles. Additionally, often our engineering leaders focus on different areas and related roles to understand if there is a job fit within the company when a candidate does not excel in the specific job in which they applied. We appreciate your feedback and will ensure our candidates have a clearer understanding of job fit as they move through our interview process.
