Hi, What kind of algo questions can I expect in the 90 min online exam?
This is a weird question. Just go on leetcode. Thats what you can expect, medium and easy
Great advice. I just looked up the two problems amazon asked me to solve in the 90min. Equivalent problems were both marked as medium. But of course leetcode tells you a lot of detail about the problem. However, they were very cleverly disguised. It wouldn’t be possible to just search for the answer. Expect a stub method + unit tests available, and a variety of language choices. You have to get it to pass all the unit tests + hidden unit tests. The UI wasn’t very clear at showing when tests timed out. This was really a time constrained exam and amazon only cared about correctness as measured by tests you pass. This does mean, however, that you have to have okayish time complexity to pass some of the tests.
Look up the answers to the questions on google once u start the exam
One easy and one medium. And bunch of behavioral multiple choice questions.
Tagged questions help?
I think the easy one was tagged. Don’t stress abt it. When I took the test I had no idea if it was tagged or not. I passed only the visible test cases on medium n got an onsite invite. I didnot lookup any solutions etc while doing it.
Expect them to not actually call out what the algorithm or even the problem is, rather that they will phrase it as a business problem.
