Project assignments change all of the time, and getting assigned to a project you don’t particularly like as a new hire shouldn’t necessarily be a deal-breaker. Take a look at the company as a whole. Is the company growing? Are their other teams or better projects you could eventually move on to? For me, the answer to those questions would influence my decision on whether or not to stay. In any case, one week is probably not enough time to tell unless the manager or culture itself are unbearable.
