I applied through college or university. The process took 2 days. I interviewed at Tech Mahindra (New Delhi) in Oct 2015
Interview
Great interview process, panel was mostly from elite universities like University of California and Harvard. Questions tossed from all fields. Value interdisciplinary expertise and skill set. Be ready for coding questions from one, electronics questions from other and then even about concepts like moment of Inertia, kepler's planetary theory, etc! They are looking at your confidence and presence of mind.
interview was average not to easy not too tough, asked few questions regarding coding as well, first was telephonic interview with the HR and second was technical interview with the manager, overall was good
I applied through a staffing agency. I interviewed at Tech Mahindra (Pune)
Interview
3 processes. smooth
technical round, manager round with hr. No written test only logical presentation. very easy process. so you can go to the job no issue. it is easy.
no work pressure
written exam followed by interview with hr and it was moderate interview . But documnet submit process was very lengthy and making bond for 2 year was worse thing which kills some future.
