I applied through an employee referral. The process took 2 days. I interviewed at IBM (Bengaluru) in Apr 2016
Interview
It was a internal reference. Took about 2 days. Had a excel test and a the final round with the Sr. Manager. Everything went well. I was told they would get back to me on compensation in a week's time. A month later I get news they they are not able to match my salary. Even my current CTC. Forget about my 30% hike I've asked for. Really sad at the way this went. No proper response or communication from the IBM.
I applied online. The process took 6 months. I interviewed at IBM in Jun 2015

final interview
you need to revise your math skills really well as it is essential to reach a decent score in the first test and then it depends on the role you applied for as for some positions you may be required to repeat the test during the assessment
I applied online. I interviewed at IBM (London, England) in Jan 2015
Interview
I applied online and instead of submitting a CV they ask you to answer their set questions. When you get through this stage they ask you to take an online aptitude test. This was the easiest test of all major companies that I have taken. After this you go for two formal assessment centres. During the assessment centre you are asked to take one more IQ test and then there are a series of one on one interviews and group tasks. The whole event runs very smoothly and is done professionally.
