Most people with well-paying jobs decide to take an MBA program simultaneously. You can discuss hectic schedules and the need for more dedication in both segments. However, if you have resigned from your last job, the interviewer will ask why you couldn't do both. It is better to answer this question genuinely. Your response can be, "I decided to leave my last job, as I believe I had to give my 100% to an MBA degree to get the best out of it". You can also state that you currently do not have financial responsibilities, and if there were, you would have chosen to multitask.
