what do you think is the minimum reasonable time I should spend at one job before looking for something new?
and if the time frame that I wil be able to handle is a year or a little less, what kind of jobs can I look at applying to move into the more business sector of biotech?
I would say 2 years. Any less than that, and I will be asking you what happened. At two years, in a travel job, you are fine. It won't raise eyebrows to move on. If you last less than a year, it will raise big red flags. I wouldn't take a risk on you after that, as at that point you have left a Ph.D. at less than 2 years. You have left a job at less than 1. What makes me, as a hiring person, think that you will stay with my job? You will, at that point, have shown no ability to stick with anything. I would be looking at you as someone who would come in and leave. Since hiring people is a real pain in the butt, I am very biased against doing it more frequently than I have to. Part of what I take in to account is how long I think you will last. Less than 2 years = bad. More than 2 = fine. I don't think I can tell if you will last 3 years or 10 years, but don't really care.
My personal rule is not to move more often than every 3 years. Others set the bar at 2 years. I don't know of anyone who sets it below 2 years, and whose career I would be trying to emulate.
I think you were absolutely right about suspecting that 30% travel sounds too good for AS. THe other person I interviewed with already stated 25-50%, which leaves me concerned that it will go up over 50 rather fast. :(play to something I have said before. You have no idea about how you will handle travel. I would expect, with an FAS job, to spending more than 50% of the time on the road during some periods. The end of a fiscal year / quarter would be a time when I would expect you out constantly. Early in the quarter, not AS much, but still.... I can't help with this part, but if you make this jump I think you have to be willing to stick it out for at least 2 years, or you should expect to have problems getting the next job.
I am excited as hell to travel, but I need the travel time to be shorter than the time spent at home, I think... to retain my sanity.
