Formal interview with questions on the company, CV, past experiences and technological understanding which lasted for a hour and was followed by a walk around tour of the site. Overall a straightforward process but communication either side of the interview was slow

What is the most challenge job you faced in your previous company? how do you handle this challenge? How can you contribute to our company? Tell about yourself? What is your strength and weakness?

Fairly standard, but honest. It was pretty standard for a large company. I got to meet several of the team members I would be working with. Overall a basic interview process.
