Sandvik interview questions

I applied in December 2022. The process took 5 months. First round was a personality and aptitude based online assessment. Second round was a telephonic call with basic HR questions. The final round at Sandvik's office involved some group activities like puzzle games, case study assessment and 1:1 interview. The HR seems to be unprofessional and doesn't respond to any emails, if you don't hear from them in 3 weeks, then the application has been unsuccessful.

First interview with HR recruiter to go over resume and skills. Next round interview with hiring manager to go over skills and detailed experience. Potential third and fourth round interview, but was ghosted after hiring manager interview. Tried contacting recruiter twice with no feedback whatsoever, completely ghosted.
