How can I get into a different industry?
I have a master degree in non-business subject. I joined a commercial company in the same field and had worked in marketing department for 7 years. My role was expanded to cover Asia Pacific region 2 years ago. I quited my job recently because I don't want to travel too much due to family reason. Opportunity in the same field is very limited and only junior posts are available (senior posts are usually located in China); but it seems that I'm too experienced for junior posts (tried a lot and no luck). So I want to get into different industry because of the extensive marketing experience I have; but I don't have marketing or BA degree (I do have a diploma in marketing).
I'm thinking if I should get a MBA now or master degree in marketing or finance; but this is big investment and can't guarantee a job later. Or will it be better to apply for junior post in different industry (but people may think I'm too experienced)? Please advise.
