Pros
You do get to make your own hours and create your own schedule but those are the only pros
Cons
I just started as a level one background investigator. I had 6 weeks of training, and once you get into the field it seems as though the training was a waste. Nothing learned in training comes close to what you actually do. It is also hard to get a direct answer from anyone. If I ever have a question I have to call at least 3 people all of which have different answers to my questions. It seems as though no one exactly knows what they are doing. You are graded on your quality and quantity you can produce with unfair metrics. It is very hard to reach an acceptable score when everyone you need to interview will not return your calls. I have had to show up unannounced at a workplace to try and track people down. They don't tell you at all what it is you will be doing when you accept the job, make you sign a year contract, and then you actually find out what you do on a normal day. Also the pay is not substantial enough for what you have to do everyday and it does not differ based on your job location.
