A good stuff by David Beisel who have questionaire ready for you to be asked to your employer (if it is an startup).
In startups you have many opportunities to learn new and do unrelated professionally enriching things . You get chance to wear different shoes and you can figure out which fits you best. You are always in radar of management due to small or no hierarchy (perform and rise x 3) but as Fred says there can be some issues.
I have started my career with an unlisted Startup company and these questions may not hold true for some scenarios:
1. Startup management will only be interested to answer these questions when you are getting recruited for key position in the company.
2.Company I joined was a self funded startup company, kinda new software business for the business house and hence I guess exit strategy was not in place.
So, for entry level or candidates with some experience, just forget about 7 questions by david. Work hard and get benefited from being in startup.
