Ask the guy about his pass/fail ratio for his students. Ask him what his general philosophy is regarding ground and flying. Ask him how fast you can get to solo, if he tries to answer that by saying depends on your ability to learn. Don't use that guy.
Use the guy that says soloing will happen automatically when the time is right. The goal is safety. And learning the basics.
Also, ask him how often he grabs the controls. If he says when he thinks it necessary, don't use that guy. The CFI should let you control the plane the ENTIRE time you are in plane unless you do something radically unsafe.
CTLSi are you a CFI??
I would completely ignore that post, minus where he contradicts himself.
What you want is a higher time CFI who teaches on the side from his full time flying job.
FIRST thing, chat with him about his goals, sports, where he's from etc, see if you hit it off, you need to have someone you mesh with.
If you think you could be locked in a small aluminum can with the dude for hours on end, next step.
SCHEDULES, is your free time matching with his free time, if you can't get two flight a week out of him, it ain't gona' work.
Next his credentials, ask to talk to a few of his former students (2 or 3), they should be recent, you want a guy that is still keeping his CFI seat warm.
After that how much total time does he have? Is he a commercial pilot or an ATP? I'd want a ATP if I were you.
does he have any tailwheel, acro, glider or chopper time, the more diversified the better IMO
I'd also ask if he is a gold seal CFI, this at least tells you that he is/was a very active CFI and has/had at least a 80% first time pass ratio. It's easy to tell a gold seal CFI, the FAA symbol on his CFI ticket will be gold
Then just go do a 30min discovery flight with him, see how you like it.
The DONTS
Don't join a club, buy a plane or make any other huge money decisions until you get your license, I can't tell you how many people didn't end up finishing and had to whore out all the fancy expensive dodads, headsets, iPads, planes and club memberships they foolishly bought.
Just find the cheapest plane to fly in, it doesn't have to be pretty, just airworthy.
Most importantly, ENJOY!!
