Thank you so much for your kind reply. Actually, decision to back to school is not easy to make especially for MBA programm. My division is full of veterans with decade-long experiences in this field,so promotion is can not be expected in short term. Absence of knowledge in relevant field now becomes a bottleneck for my progress. It should be noted that I ever had 1 year working experience in a domestic design company before graduate school and 1 year interesting experiences of part time job in Crazy English(Liyang) as a teacher, lecturer and marketing leader in whole china. I hope that McCombs could serve as a stepstone for my career and channel it into real estate investment area. BTW, I am close to 30, I am afraid that older age will shadow my application and following job hunting if I apply 1 year later. If you can further advise me on points above, I will greatly appreciate that.
