Hi Hoat
You are very young so there are a lot of chances is waitting and coming to you in the future. Google is really a great opportunity, but you should have considered and choosed what is the best practice actually. I have known that: youth always have a lot of dreams, ambitious .... and would like to meet some new chanllenges, new chances. Beside that, you also have known exo platform company is very good in Ha Noi where you are having the happiness time, good working eviroment, chances for developing and becaming your carreer in here ... You are the last student year in University that means you have been farming tree and now its time to pick fruit, although the first fruit not sweet, luscious ones but that is you have done after working, studying so hard. So, why do not you continue to work in exo platform where you have been sowing seeds and it has been germing, so why do not you wait to harvest. I also wondering if exo platform has good environment same your opninon, why don't you try to disscuss with Officer Manager about integrated your applications for Music to EXO Product such as eXo Social or eXo Portal and they will be able to completely help you to develop, improve your product and in the future you can become a Product Manager EXO Social Music... I think: that is great chance and its possible.
For Google, I think that this is only a "strategy" because there will be many changes and happened in 2 years ... Whether you can work completely in 2 years with them and then whether they have established VPĐD in Vietnam or not? This is a completely question and strategy because of the biggest competitor of Google is Yahoo has done to establish Yahoo Vietnam Company in Viet nam.
There is only my opinion. Of course the final decision is depend you. There are a lot of chances, but its important for us how can get and find favorable environment to develop and implement opportunities became true and success is very few. Please consider carefully and I wish the best wish for you in the future
Thank a lot
