How much detail have you all been providing in your application about things such as "Reason for taking on this role" and "Reason for leaving" under employment history? Do you just provide a quick answer to provide comfort you weren't fired, or does the AdCom actually want details around your decision-making?
Really depends on your career. If I see your CV, is it obvious why you made certain moves perhaps because that's a common route to take for e.g. you worked for two years in IB and then went into PE. Probably don't need to explain those in alot of detail.
If you have made moves, the motivations behind which are less obvious, you should explain that.
In my case, I held my first job for 11 months and then moved and then held my second job for 10 months before I moved to a third company where I stayed for 4 years. I then stayed at a fifth firm for 12 months and and a sixth firm for 4 months.
If you read this, it comes across as having lack of direction, probably reeks of professional immaturity etc. So I had to explain why I made those moves for e.g. I HAD to make the first move because my team left and I had no supervisor for 2 months and that is not a situation you want to be in as a new graduate. Similarly I moved from the second to the third firm because it was too good of an offer to decline (moved from sell side research to a portfolio manager role).
That being said, I would say, even if your career transition makes sense, use these small sections to add weight to your application. Let's say your first job after uni was IB at a boutique firm. Probably don't need to explain that right, its a job everyone wants? But you could say "I had an offer from a bulge bracket and a boutique but I chose the latter because my research told me that boutiques are better places to learn and I will get more responsibility" That gives me a snippet into how you make decisions.
Hope this helps.
