Boss said I should care more about growth than salary early in my career

Context: I made a reddit post a few weeks ago discussing some poor work life balance at my current role at a startup that I've worked at for roughly 2 months now. You can check it out on my profile, but essentially I finished my work for the day, left 5 minutes after I was supposed to leave (5:05) and was later scolded for doing so, because apparently I need to wait till my project manager leaves first, and if she is still working I should look to contribute and help out. This is because we are a "team", despite my project manager saying Im good to leave. I agreed with the sentiment of the comments from the post: I should silently start looking for a new job. I received and accepted a job offer at a larger company (fortune 250), more pay, better benefits, remote work, very stable work life balance. I tell the CEO of the startup today that I found a new opportunity, accepted it, and will be leaving. Immediately I'm asked why I'm leaving, what the company is, what the role is etc. He gives me this monologue how at my stage of my career growth is the most important, and that he wasn't aware that "I valued salary so much at this stage of my career" and that "the salary will come with time". He said his startup is the best for growth because its directly interacting with the customer. Goes on saying I haven't reached the stage yet where I've "outgrown the company" yet. Says when he was my age he was prioritizing growth. All in all this is my first time actually resigning at a company since the rest of my employment was contract work, and it just felt really bizarre. No "thank you for your time" or "I wish you the best" or "we are sad to see you go" or "I understand this is what you think is best for you". Just a monologue as to why his company is superior in growth compared to the larger company and it felt like the whole conversation was me having to justify myself as to why I am leaving. Then I ask what the next steps are and he says to push all my code to GitHub and then he will terminate my access, and will notify the appropriate team members and that I will be contacted for an exit interview. Obviously I don't care since I'm leaving, but what does everyone make of this? Is this normal? Update: Had my exit interview and his question was “How do I prevent this mistake again?” “What can you tell me about yourself so I can predict in interviews that someone like you would make a decision like this?” I told him that the work life balance, people with a lot of hobbies who are passionate about them will want stable hours. His response “the job description says this is not a traditional 9-5” “all customer facing jobs are like this” then he mentions “you are the last junior developer we will be hiring” Lol
