I applied through an employee referral. I interviewed at IQVIA (London, England) in Mar 2025
Interview
I received a link to complete an aptitude test without a clear deadline with a statement to take an assessment as soon as possible. It was not easy for someone who had not done it before especially timing. You have to practice.
Interview questions [1]
Question 1
There were 2 blocks: 25 min for c. 18 short questions and then 45 min for 16 more complex questions
The process included a HireVue interview, a behavioral screening, and multiple case interview rounds, including a group case interview. Everything was conducted online. The cases were a mix of individual and team-based exercises that assessed problem-solving, communication, and collaboration skills.
It went well. The interviewer was friendly and the overall experience felt comfortable. Expect a few puzzle-based questions along with detailed discussions around your projects, problem-solving approach, and decisions you made while building or handling different machine learning or data science tasks.
Applied through handshake. Interview was two rounds and one case interview. Case interview was pretty straight forward. Asked a typical sizing question. Can prepare for these kinds of questions online
