I applied through college or university. The process took 2 days. I interviewed at Mu Sigma in Nov 2014
Interview
The recruitment was through the college campus placements.Around 450 students sat for the process.
The recruitment process took 2 days.First day was only online aptitude exam and the result for the shortlisted candidates was announced the same eveningand around 150 were shortlisted.
This was followed by a written pseudocode and a written case analysis exam and after this shortlisted candidates were announced. they were around 60.
then came the GD and video synthesis round and candidates were reduced to 30.
this was followed by HR interview, yes to my surprise also. I had read everywhere that Mu Sigma conducts a very logical technical round where your analytical skills are tested with guesstimates and case studies but to some reason(dont know why) it was omitted.
In the HR round they asked me whether I had a girlfriend and what is she doing, why didn't she sit for Mu Sigma and where is she going to be posted and where am I brought up and what don't I like about Delhi. That was it and I was not selected.
I was quite shocked because I was expecting to get an offer. I didn't expect from an experienced analytical company to judge a candidate on the basis of an HR interview and that too of this kind. In my opinion they should test a candidate's communication skills, analytical aptitude and his attitude towards the company's work and other skills if any and not on stupid questions.

It was good.
First round was technical assessment which consists of 48 questions.
Second round was AI bot round which primarily focuses on your resume. It goes on asking in-depth questions based on your responses.
Third round was HR round, in which the HR asks few questions regarding the skills you added in your resume.
The team was supportive.
