I applied through a staffing agency. The process took 4 weeks. I interviewed at ISG Ltd (London, England) in Mar 2022
Interview
Was ok but long. Interviewer knew what to ask and was kind and respectful. I understood what they were looking for, so it gave me clarity on how to correctly respond.
I applied online. I interviewed at ISG Ltd in Dec 2025
Interview
Applied online. Was contacted by recruiter. First round was quickly scheduled. Went well. Next round was with another associate director who wanted another opinion. Then again the third round with a director who went in depth of the resume line by line. I thought the discussion went well but the feedback was opposite.
There were moments of lull when no inputs were provided for weeks. I had to reach out to the recruiter to get the input.
Straight forward, formal, understanding with head of department. Relatively easy questions and more about personal work ethic than knowledge as this was for early career role. Welcoming office and professional atmosphere.
