Hello Pavel,
I consider you a strong candidate for INSEAD. This conclusion considers all the factors – academics/tests, career specifics, and additional activities. I say “strong” because not only are you well qualified, but you also represent an unusual segment of engineering – this helps to mitigate the fact that people with technical backgrounds tend to be over-represented.
While you are a potentially strong candidate for INSEAD, it’s still a reasonable reach – because it is for everybody. So you should
prepare a stellar application. Also, while the GRE is accepted and your score is strong, adcoms still are more comfortable with the GMAT, so if you can do that test and score well, it would further strengthen the application (though, it’s not worth pursuing if it would take too much time/effort, because you’re well-qualified without it).
Other programs in Europe to consider would be IMD, LBS, and IE.
