Ha I was given one of those when I graduated and interviewed for some random firm (in US), I don't know if it's Aspiring Minds but it was clearly from India. They really go to an extreme length to monitor the tested and I felt very uncomfortable during the whole thing.

The camera's on, Document.hasFocus() is obviously also on, I use multiple screen and you can't move your mouse out of that screen. The test questions are repetitive recital garbage that ask you to recite java syntax and concepts. All in all I would judge it as a complete failure in selecting for technical talent.

All you need to prepare for this is to recite some book about locks or thread and names. And have the coding ability to write hello world level programs in Java without a linter or autocomplete, god forbid you forgot how to use Scanner interface.

I might sound salty, but I didn't need that job and I'm in a much better position today. My opinion is that those filtering tests are loads of crap.
