I'm fresh out of grad school and busy interviewing for my first job (in roughly the data science field). I've interviewed at two companies, both of which look like they can offer me great experience and competitive pay. The one (Company F) is an online fashion retail start-up of about 140 people growing massively, the other (company M) is a worldwide well-established market research company.
Since they are roughly the same in terms of the quality of experience that I'll get, and the salary, the trouble I'm having is this: Company F's offices are on a single floor of a downtown building: one big open-plan room with literally just lines of desks, with every department of the company sharing this room (and therefore everyone able to see each other etc). No kind of cubicle divisions at all. Also, being into fashion (for young people), there are lots of fashionable/hipster types walking around and to have them visible to me the whole time while I am working seems a frightening prospect. On the other hand, Company M, being so well-established, has its own spacious offices in a leafy suburb of town. Many people there have their own office, and the rooms that are shared are quite spacious and have cubicle divisions.
I am mostly an introvert, and the thought of large groups of people makes me feel a bit nervous. I also struggle to do deep thinking when a lot of people are around me, having always avoided the big library halls in college in favour of smaller study rooms. On top of that, I tend to do my best thinking when I am pacing around the room, which would look very strange and stand out a lot at Company F. I know it might sound a bit silly letting the layout of a company's office being a major factor in one's decision on whether or not to take a job, but for me right now it is the only real discriminating factor. I am really concerned that I wouldn't be able to work effectively, or be happy, in Company F's huge open-plan office.
But maybe I am all wrong about that. One idea I had was to "intern" (probably for free) for a day at each company to see which is a better fit (more specifically, to see if my prejudices about Company F's office turn out to be true). Can anyone offer any tips on how to make this decision?
