For the technical operations team specifically, expect to be excluded from most in-office socials; this is just the nature of the job, needing support constantly during business hours, so happy hours or company-wide leisure activities are often skipped out by the team to keep up with work (not to say fun can't be found within the team itself, it very much can be).
Additionally, if working from home is a deal-breaker, it should be noted that after the first 6 or so months of training, work from home is a consistent feature of the job about half-time.
