Cisco Developer interview questions

Online coding test with some LC easy/mediums. Virtual onsite consisted of three interviews: Technical (some basic leetcode-like questions): Was with a friendly SWE and really easy. Resume Review (?): Conducted with some interviewers who showed no interest in interviewing or asking me questions. Could barely speak English and had their cameras off the whole time. I asked most of the questions. It seemed like they had already made up their mind before the interview or something. Behavioral Interview: Your typical behavioral questions. Overall: I don't know how a company lets people like these conduct interviews with no training. Very negative experience. The recruiter was also very unresponsive. Please don't waste hours of someone's time when you have no intention of hiring them.
