I think the easiest and most overlooked piece of advice revolves around cell phones.
When you start a new job, under no circumstance should you give them your personal cell phone number.
Tell them it's inappropriate, tell them it could turn into a conflict of interest, tell them you don't have a cell (true for me), tell them you can't afford a cell, tell them you can't afford roaming, tell them you only have data, not a number, tell them anything you have to so you don't give them your personal cell number. Don't ever, ever let them install anything on your phone either, "BYOD" style.
Same applies for your home number, if you have one, and your personal email address. Setup a different email and google voice number for the purposes of interviewing, etc. Once you have a job, don't respond to it "real time".
Now, if they want you to have a work cell, they can provide and pay for it, and before you put a hand on it, you make them very, very clearly document under what circumstances and times you are expected to answer that phone, and what compensation you get for doing so. If they won't provide extra compensation, you make it very clear your home commitments (kids, sick family, make something up) are your priority, and you won't be taking that cell home with you. Leave it in your desk drawer at work, turn it on at 8:30am and turn it off at 5pm and leave it there.
If your employer won't accept that, find another one. Life is too short.
