I have been working here for past couple of years. I am a permanent resident. I have accepted a job offer at different organisation and about to join in couple of weeks. I just started reading reviews in various job sites and glassdoor and many have commented having to slog often, work overtime and be available on call most of the times.
I would like to understand what's the usual overtime in software industry and what if I want my own time as I have family with kids and need to take care and spend time with kids and don't want to be on call availability at all times.
In my current organisation, I start by about 8:30-9:00 would usually leave by 5 and no one asks a thing. Occasionally if there are any issues or deadlines to be met, I've spent extra time without anyone asking. Is it okay to just shut down the system at 5 and leave?
The reason I am asking the question is my current company is a small one and I am moving to a larger organisation and I am not very familiar with practices in large organisation.
Depends on the culture and if the company values their employees. IMHO do as little as possible otherwise they will expect it and it will become the norm. As for on call read the job offer / contract you have signed for the details if there is any on call as this is where most large companies get work for free and after hours, which unfortunately has become the more the norm now than say 10 or 20 years ago and it sucks.
