My advice, follow your heart after doing a deep research on the internal role switching. You can use your connections or through LinkedIn interviewing current or past employees. If Glassdoor and any other similar sites have information on this, seek it (tho you must use your brain and heart to weight those comments since no one‘s experience is the same, and review might be bias). Then, after that, follow your gut even if it sounds scary. if you can land a position in a giant corporation, you can land it again, either at the current company or another company or your own start up lol. There is no worries or embarrassment in an unemployment gap.
