Hi,

If you are concerned just for a easy call.

Choose a specialization which is similar to your work experience. (Eg Information Management for an IT Software Developer or Engineer)

You can Choose Marketing/Finance if you are having 0 or less than 2 years work-ex.

For a higher workex 2+ , you can go for Operations.

B. If you are concerned for your interest area.

Choose the specialization you want to study as your first preference without thinking if you will ever get a call or not . ( You should not end up again converting it and thinking it this was not your interest area)

Hope this helps

Wish you luck
