I applied online. The process took 2 months. I interviewed at IBM (Ilmenau, Thuringia) in Apr 2015
Interview
Call Interview regarding internship of 3 months in IBM in the field of Data Analysis. A panel of 4-5 IBMers were there and asked questions about my past work experience, skills and some of the projects. The interview was a telephonic interview and went very well. I got selected for the position and later got an offer to pursue my Master Thesis with IBM too.
Interview questions [1]
Question 1
Asked about my work experience, my current Masters study, my research projects I worked upon and my technical skills
First round was a case interview and final round was a behavioral interview with a more senior member of the team. Each interview was 45 minutes with one member from the team.
There was only 1 round of interview. Heard from recruiter 1 month after submitted application. Interview was 1 hour and did not seem structured at all; it went over a mix of technical and behavioral topics.
First stage of CV application, followed by an in-person assessment centre, then final interview with hiring manager in person in Southbank London office. Many assessment centres were running throughout 2017 when i applied.
