Shell Customer Success Specialist interview questions

It made me feel sad when one company won't inform you the result of your interview, so I guess I failed the final assessment. This company ghosted me even though I sent a follow up email to the recruiter. I have a lot of respect for the company but not a remarkable experience for myself. Initial interview will be conducted by the recruiter, basic questions about your past experiences and a little bit of situational questions. Next will be the final interview with the hiring managers, mixed of technical and behavioral questions on which you will answer using STAR method. They will advise you to wait 2 to 3 weeks for the result but will never get back to you in reality.
