Hiya,
Hmm, interesting scenario... and tough to advise on without a lot more info about your profile and goals etc. My initial reaction would be that while yes I agree on pluses of the opportunity you mentioned (teamwork, project management, networking etc), I also agree with you that it would likely raise questions and the pressure would be on you to describe the 'why' of changing directions like that especially if not related to your longer term goals.... so if you feel uncertain of how you'd explain it, that could come across in a negative way in your apps and/or interview.... if on the flip side you determined it would be beneficial to your long-term plan, then that could be a different story. Good luck on the decision.
