HPC and big data are exclusive to the USA. IBM, Intel, Cray, NVidia, Amazon, Nokia, Google have those needs. Its actually quite easy to name places. That being said, showing an interest in Java is an almost immediate disqualification. You need to be able to answer questions such as how to vectorize a loop, structure of a makefile, how to build a cache, what is thunk, pthreads, and sometimes you may need to be aware of BLAS. During an interview I was asked 'who mom likes'. Off-course my mom likes me!
