I think their selection process is very fast: after sending my application, they asked me to take an online assessment on Java (The language I choosed). If you don't know java very well, it's difficult, but google can help! :) Then I was asked to take a phone interview.. They send me this file: Dependent on programming language proficiency, you can be asked technical questions around but not restricted to the following areas: C • Pointers • Variable types/scope • Program architecture (memory, stack, heap, registers, etc.) • Read/write small code examples. OO & C++ • Object Orientated Design • C++ constructs that support OO Java • Objects and Classes • Java virtual machine UNIX • Unix architecture (file system, piping, stdin, stdout, stderr, etc) • Basic commands Data structures & Run-time analysis • Basic data structures • Run-time analysis of data structures Now, I stated my proficiency language was Java, and the phone interview was about C.. They asked about pointers, heap/stack, bitwise operations, hashtables.. I have not been programming C since more than 1 year, so it was more a memory exercise than a job interview.. AN hint: they actually work with C++ and C under Unix, so i suggest to choose directly C and refresh this language instead of bothering with Java.
