Weirdest job interview ever.

I 41f had an interview with a M25yr team leader, via teams for an HR/ Recruitment consultant role. Team leader seems ok , he starts interviewing me, then stumbles over his words asks if he can start again and then states. “Sorry Im actually not confident interviewing people and I hate this part of my job” ( wtaf is this unprofessionalism) I sort of laugh it off and ask if he needs to take 5 and come back. He then jokes oh maybe you should just interview yourself cause I can see you have the experience, looks like you know your way around the database we use and I’ve already done referencing and police vetting. Then veers off to talk about their union and how “most everyone joins” asks what my notice period is and if I can start in 2 weeks. I ask if there is any other question he wants to ask me like actually interview me. He says “no we are good to go, I’ll touch base with our Hr admin team and they will send a contract out in the next few days” Wait a few days hear absolutely nothing back, contact HR of company to see when my contract is coming the lady I spoke with says by next week Monday and that I should hand in my notice to my current employer cause they want me to start as soon as I can. I’m getting a weird feeling and don’t hand in notice . Monday comes by and get nothing via email, contact them on Tuesday only to be told actually I have another interview with the manager of the team and they will send the invitation via teams and for me to “keep an eye out” I say well actually I’ve been verbally offered the role by not one but 2 of your staff & that my contract was being sent on Monday gone. They apologise and say actually that’s not correct I got my wires crossed. I then send the Hr lady the teams dictation of the interview with the team leader & email their HR correspondence highlighting where I was told to “hand in my notice with my current employer” then tell her thanks but no thanks if this is the way your junior staff conduct themselves and I would be trained by them. I then sent feedback to her in regards to my experience with their HR process, citing that the team leader who hates interviewing should not be doing it. Like come on wtaf are you doing there.
