Ipsos Research Executives interview questions

I applied the post through online application. HR invited me to a interview after a week. The whole interview process took about 2 hours. The HR manager would ask you some basic questions. Then, you had to complete a written test in 1 hour. Afterwards, the HR would collect your paper and the research team leader would immediately have the 2nd interview with you. The whole process is not very challenging, but you definitely need to prepare.
