Pros
1) Work ambiance is good(desk facilities,Desks,Laptop). 2) Extra activities are regular.( Eg: Independence day celebration, AON mela Etc). 3) Regular Team outing.
Cons
1) No development growth in IT, because AON is not IT company. 2) As there are less(2)technology departments in AON, so no cross technology training or dept shifting possible. 3) Management is not fair and autocratic. 4) There is always a chance they may shift you to Support work(in shifts).[Dangerous it is, your learning will stop and very difficult to get into another IT company next time]. 5) There many things (Last day letter,relieving letter ,Experience letter, Form 16) which are automated in regular IT companies are not automated in AON we have to write mail and follow up. Note: My Review is only related to AON-Bangalore 'IT department'.
