SK Battery Manufacturing interview questions

It was one round of interview : 70% technical and 30 % personal questions. Like as always starts with the self-introduction about 1 min, and then background checking. There are like 5 managers but only 3 managers with their video available. There are the manager in charge of formation process and MI engineering. I was asked little about the process of recharge and discharge process and what each components of cells : active material, binder, and etc does. Later, it was more on statistical tools like SPC/DOE and vision related AI/ML questions. What is rule-based? What are differences among detection, segmentation, .... It was supposed to be 30 mins but little over 10 mins or so.

A long wait. A lot of people placed in an auditorium by numbers. Once you meet with HR, that last about 15 mins. Brief questions about past work experience. Size you up for uniforms and boots
