Nokia recruitment was a pool campus recruitment. It consisted of 3 rounds; Aptitude test, Technical Round, HR round.
The aptitude test was conducted by ASPIRING MINDS (AMCAT) and consisted of five sections : Technical( OS, C++,C , DATA STRUCTURES), QUANTS, VERBAL, LOGICAL AND PROGRAMMING (C++ OR JAVA). AMCAT is a question adaptive test. So for me , the level of difficulty kept increasing. For aptitude, please refer to RS Agarwal, Indiabix , geek monkey.
36 students out of 200 were shortlisted for further procedures . The interview was pool campus ( my college and another college). In total , 65 students were interviewed . During the technical interview , ALGORITHMS, DATA STRUCTURES( LINKED LISTS AND TREES) AND C++ questions were asked for me . Questions vary depending on your resume . So make sure you know everything in your resume .HR was simple. Overall, a very good experience. Be strong in your basics.
