Personal profile:
almost 30, male, Chinese living in western Europe for 6 years, GMAT 720(v36, Q51), IELTS 7.5(speaking part is only 6.5 which should not be since English is my only working language).

Academic background:
1. Bsc in Computer Science in China, 7.7/10 (to answer your questions below, I'm going to assume this was around the top 50% in class)
2. Msc in Information System in the Netherlands, 7/10
3. Advanced degree program (with a professional doctorate degree) in software technology in the Netherlands

Work experience:
1. Two years as the software engineer in China for a large Chinese company. Built and led a team of 4 engineers and a few small projects, though without the manager title. Also travelled a few times for customer service
2. Two years as the software engineer in Europe for a Fortune200 electronic company (like Simens). As the owner of some key product features, I mainly work on the software development, but also on product development, customer service, and lead a few cross-department and international assignments. As the only representive of my department colleagues, I was also seleted to work with other committee members on improving the employee engagement of our business unit.

Extracurriculum
I am always active on building and maintaining the online alumni networks for my high school class, my university class and I am the cofounder of the largest professional group of Chinese exparts in the Netherlands. I also led a large student association of more than 100 when I was at university. In the past 2 years, however, I didn't contribute to community service. But I am a top player of the soccer team of our business unit, and played in this years's corporate international soccer tournament.

Career goal
My real dream job is strategic consulting or VC in the IT industry. To better associate my goals with my past experience, I plan to mention in the essay my plan to work for IT consulting after MBA, or to build a IT consulting start-up in China. I have IT work experience in China and Europe, and I have domain knowledge of IT systems for power energy, high-tech and medical device/healthcare.

My question:
1. How do you think about my career goal? Does it look ambitious enough and also realistic?

You are going in the right direction. Based on our experience, your career plan is likely to be stronger if you:
- Focus either on the start-up-in-China option or the IT-consulting-job option. I like the first option a bit better - higher stakes in the long term, well connected with your Chinese background, and possibly igniting the imagination of adcoms (in the minds of many admission committee members, China is still a fairly hot name economy-wise, with promising entrepreneurial opportunities).
If you go for the IT consulting job - are you able to get an offer from the fortune-200 company for a position you may undertake upon graduating?
- Consider focusing your career plan on either energy IT or healthcare IT (pick the one you have more passion about and/or more experience in).  

2. What schools are my stretchs and fits? I am planning to apply in Europe and US. How about Yale, MIT, Duke, Ross and LBS, Insead?

Based on the info you provided, and under the assumption of strong essays and recommendations, my impression is that you'll be a competitive candidate at Ross and LBS, between competitive and stretch at Yale, Duke and INSEAD, and stretch at schools such as Wharton and MIT. If you're able to show a clear path of career progress, and if your class rank is better than the one I assumed above - this will upgrade my evaluation.

Your IELTS score passes the minimum at most programs. However, notice that most top US MBA programs will not accept the IELTS, and you'll need to take the TOEFL exam (of your M.Sc. degree was in English you should check waiver options).

3. I am considering changing to a product development job at the same campany, or to a software developer job at a famous trading firm that gives me more exposure to finance. Do you think the new jobs worth me delaying my application for a year?

Based only on the information provided, and under the assumptions that your new job title will not be much more impressive than your current title and that you will not be managing a significant amount of people, I think you're better off applying this year. You will still be able, of course, to re-apply next year if needed.

Thanks in advance

Sure. Hope this helps.

Thank you for your observations. I will admit that i am a little disheartened as I thought i would be extremely competitive at Tepper.Nevertheless, I will appreciate  continued  candour- however brutal it maybe- in your professional opinions 

I dont think the adcoms at the Tier 2 universities namely SMU COX , Tepper and Tippie would be familiar with the company that I am working for or its core competencies 

I would also like to point out that I will have around 28 months of work experience by next september- the time i would be matriculating, in the event of an acceptance   . Isnt that what counts?

The average Tepper admit has over 50 months of full-time work exeprience upon matriculation. As you go below 36 months, it gets a bit harder to get in. As you got below 30 months, it gets even harder. Therefore, I'd give the amount of work experience a small-to-medium negative weight in your case. Of course, you may still get accepted if other stats/credentials/achievements, and the quality of your application, compensate strongly enough for the GPA and work experience minuses.

Finally do you feel my queries are inappropriate for this thread , since you have always marketed yourself as consultants for Top 10 programs

Our expertise is the top-10 MBA programs. However, over the years our team (initially operating as Aringo) helped engineers get into each and every other top-20 school. In fact, at least a couple of the engineers that we helped got a full scholarship at Tepper upon acceptance.

Thanks

Good luck Burberry.
