Career Transition Advice for Executive Assistants
"I am interested in working in that domain now" is NEVER a wise way of opting for careers. Even though interest plays an important role in career selection, you also need to combine it with your capabilities, past experience, and the long-term effects.
The role of an Executive Assistant is not a bad one in any organization—better stick to it. As you are aware, Executive Assistants have exposure to a wide range of functions, including Purchase, Finance, etc., as part of their jobs. However, getting into the hardcore functional roles of any line would make your career graph 'look like' you didn't stick to any one role/function... I am speaking from the recruiter's perspective.
You surely have a very valid reason/justification to show your part-time experience ["I can concentrate on my family side, which was needed at that point of time"]—leverage it. You can also mention that this exposure to the overall operations of an organization has given you the ability to view organizational situations/issues in a 360-degree way. At your level, this becomes a major plus (it may not be viewed the same way for a junior-level employee). Exposure to the operational/implementation side of decision-making for an Executive Assistant is always a plus.
Regarding your remark "Also, the salary I am getting is very less when compared to my previous job," I am not sure how you can compare both—a part-time job salary will always be lesser than a full-time job. So, I suggest not focusing excessively on this aspect—in your interviews, suggest giving both the CTCs with a clear demarcation of full-time & part-time. Please be ready to be mentally flexible on this aspect to begin with. Otherwise, the chances of spoiling the interviews will be high—the over-focus on one factor/aspect is usually at the cost of focus on other aspects of a situation.
All the Best.
