Neste Researcher interview questions

I applied online for the position of a Researcher (Job location in Porvoo, Finland) online and the interview process lasted for about 2 months. There were 2 rounds of interviews with the R&D manager who was very friendly. There was also a 2nd interviewer during the 2 rounds of interview with the R&D manager being the constant. The 3rd interview was with a third party psychologist who performed an assessment, based on your answers to their questionnaires which had to be completed prior and aptitude tests. It was a foolproof process and completely professional. Unfortunately I had to decline the offer for personal reasons but I was quite happy with the process and the people involved.

Pretty standard questions, can find all the questions from internet and practice. Like what's your strength and weakness, what's the biggest challenge you have faced, etc. Most important thing is the experience in resume. Only one hour interview, no other prep required.
