IQVIA Associate Consultant/Consultant interview questions

It was an interview for a summer job which I got through an inside connection. There were two interviews with engagement managers. The first one was a behavioral interview with expected questions like- strengths? weaknesses? situation when you worked in a team, situation when you had to analyze data? situation when you showed leadership? The second interview was a case study on sales force sizing and physician segmentation, which was a little hard.
