Is a postdoctoral fellowship required to be a professor?

The postdoc is not a required experience to get a professor position, but we can say it helpful step.

You can understand this in the following points-

• Taking a postdoc position can be very beneficial if you are looking for a faculty position. 
• A postdoc position will help you develop your research and help you to gain the experience needed to be a professor. 
• The postdoc also earns you more skill and experience, which will also help you to get the faculty position. 
• You can also meet other researchers and get a chance to work with them
• You should also know that many faculty members were postdocs themselves and that they started their research careers during their postdoc period

It’s a common misconception that you need a postdoc to be a professor. In fact, it’s the other way around. Postdocs are often hired to teach at a university, and the professor's job is to find them and give them the details of their work. For example, postdocs often teach undergrads. If you have your Ph.D. now and want to teach in the future, this can be a great way to get a foot in the door.

There are many students enrolled in university Ph.D., and most of them want to be professors. But if you want to be one, you need to start somewhere, and most new grads are stuck waiting for a tenure-track position at a university to open up.

If you've got a doctoral degree in hand, you've got a Ph.D. Unless a university employs you, this means you need a job—which means you need to get a postdoc or another academic job. A postdoc is a research assistant who will work in your lab for a few years, providing research and intellectual support. Unless you have an idea of getting a postdoc, a whole career in academics can seem out of reach.
