How common is it to switch departments or teams at IBM?

It is very common to switch departments; in fact you could say it is the operating norm at IBM. Remaining in a position longer than 18-24 months is often perceived as a detriment internally by hiring authorities.

Relatively common, however there is an expectation that you will stay a year with a team before putting in a request to transfer teams.

Totally depends on location and what you do. I'd say IBM encourages high performers to switch every 2-3 years to grow.

Becoming more common when possible. It’s extremely difficult in major market countries especially if you’re over a certain age

Not common to switch departments but you do change projects, therefore teams. It's up to you to land longer projects.

I've seen it happen quite a few times. There's room for job changes within the company.

Very common, but most people leave the company altogether for lack of personal development and movement

Fairly common. Most spend 1-2 years ona product team and then find new opportunities within IBM.

rare. They like to lay people off left and right. Calling them "resource actions"

Not unusual. Really depends on individual and the skill sets / interests.

It is fairly common and not always by choice
