How do you respond to personal obligation on a job interview?

When an individual is on the interview table, he has to make his mind regarding his priorities. If you know your priorities and don't want to get in to any sort of obligation you should brag it on the interview table.

No organization is allowed to bound any employee in terms of resignation, until and unless you have not signed in the contract paper. It is purely up to you how you set your priorities and act according to personal obligation.
