Mr. Jeevan has provided all the basics of probation. Almost 37 years ago, I remember starting my career as a Probationary Engineer. It was with a well-known public sector company, and the probation period at that time was two years. Nowadays, probation periods are not as long.
One aspect I would like to add is the possibility of probation being extended. For instance, if an employee is on probation for six months and at the end of that period, their performance is not up to the required standard, there is a chance that their probation may be extended for a few more months. In some worst-case scenarios, an employee may not receive confirmation at all. Most companies have appropriate confirmation policies in place.
