I'm in the USA, and this (probationary period) has been the case with every job I've had in the past 30 years. I've never heard of a company not doing this in fact.
Same here. Though many mid-size / smaller companies might not advertise this fact (their HR policies are often a bit more ad hoc than larger companies if they haven't been involved in as many labor lawsuits)... but pretty much if there's an HR department, the probationary period exists.
