Solvay Specialities Interview Questions and Answers

There were 5 people in the zoom meet, including me. Rest all 4 were interviewers, 3 from India and 1 from the United Kingdom.
They started with my introduction and then moved on to the questions from my resume, starting with my internship at Samsung Bangalore and then projects.
Then another interviewer asked about my weakness and strength. Then comes the turn of coding questions.

Then come my POR and other activities.
