E&Y Taxation

1. I've got opportunity under taxation in E&Y . I actually wanted Auditing for the reason that it might be more helpful in future where i go under the Financial management line . But will taxation be pretty helpful too ? Will this opportunity help me pretty well in the future ? I dont think that taxation will be of much help in financial management . Do let me know about it please .
 2.When i was asked what about the Transfer restrictions , I informed them about the Secondment option which institute allows . So its possible in secondment right, where i continue to register myself with my current auditor and work with E&Y ?
