I had a Zoom video call with someone from Morgan Stanley. During video discussions, both parties need to switch on their webcams showing their faces, but this person kept their webcam off.

This individual was also not technically competent, which is why I believe they didn't show their face. I think people here just say 'yes' or 'no' without proper feedback, so such individuals might be hiring subpar candidates.

Furthermore, these people seem reluctant to hire others who are more capable than themselves. In this way, they attempt to maintain their job security without genuine talent.

Core Java questions.

This person was also not aware of the immutability concept properly, except what is given on the internet. I had to teach him the immutability of classes and objects, as he considered both to be the same.
