Second joining startup networks. I graduated from a startup incubator and it is a small world. You'll meet lots of driven entrepreneurs. There are so many non-technical founders that would love to have a tech co-founder (me-included).
If you have access check out demo days. You'll meet lots of founders working on interesting things as well as investors.
I'm in NYC so we have tons of meetups on all kinds of tech from different types of SQL, data science/AI/ML, blockchain, food tech, hardware, Python, women coders, etc, and whenever you go to one of these events, you will always find someone working on something interesting. Maybe see if there's a local meet-up on an industry you're interested in?
I also recommend hackathons. Could you be a mentor at local hackathons? I went to my first hackathon and met lots of driven people who were willing to spend 12+ hours mentoring or coding on the weekend.
I also heard on a Jason Calacanis podcast episode that a great place to find a co-founder are employees of acquired startups- because they see it's possible and think I can do that too, so they caught the bug.
There's also websites to find co-founders too but I didn't really gain anything from it.
I don't have 5 questions, but I have one that I always, always ask: what's your story?
The reason is, you want to dig deeper into the human inside. Don't let them focus the answer on the "shallow" story, but rather on what drives them, why they do what they do, why they started this company, how did they overcome challenges, and so on. Well, now I guess you have about 5 questions =)
To each their own method of delivering value. If this employee found a way to deliver and make the client happy with "normal" working hours, then good on them. I would congratulate and promote!
This is no joke. It reminds me of when Skype used to be secure then somehow a backdoor was introduced following (or before?) the acquisition by Microsoft. History repeats itself, and humans have yet to learn from the past.
