Each role is different, however, when interviewing, I expressed how important a separation of work and life was in determining which company I wanted to work with, going as far as saying it was my number one priority. I was assured hours were close to normal with a Monday through Friday schedule and very occasional work that may exist outside of regular hours. Upon joining the company, which took nearly two unexpected months in normal background checks and red tape where income was lost waiting, it was immediately clear that the expectations of time included major inconsistencies including overnight weekend work, meetings as early as 5 AM and as late as after 11 PM (depending on time zone), often back to back, to account for a worldwide team.
Communication is BRUTAL as it is almost completely based on very noisy emails and the dreaded Skype for Business, making collaboration incredibly difficult. Expect access requests for basic functionality in your role to take up to three weeks as you sit and wonder if you actually even get to do your job. Expect incredibly vague definitions of work responsibilities and to generally feel in the dark about expectations.
Overall, the job that was described in interviews and the job that truly existed were very different. It would have been quite a bit easier to cut line early upon realizing this mismatch, but the nearly two month process it takes with no income to start working makes it difficult to come to that decision, so figuring out how to make it work is necessary.
