Should I be able to solve leetcode hard problems? I am a front-end engineer with 2-3 yrs experience.

How would anyone here know about your ability to solve hard leetcode problems? 😂

Without any kind of practices, the answer is NO.

I think OP is asking if it is expected to be able to solve hard leetcode problems for interviews. The answer is yes. Start with easy ones and medium before jumping into hard ones. But you would need some practice before you start giving coding interviews

I recently interviewed with a lot of companies. Surprisingly barring few not a lot of companies asked hard questions. Infact most even didn't ask medium questions. Most of the companies focused on what I've done in the recent past and what decisions I took and why for doing whatever I did. Some companies did ask the hard questions but with decent amount of practice you should be fine. As mentioned earlier start with simple and progress to medium before jumping to hard.

Curious. Aren't you losing any stock options you might gain from the Cisco buyout?

My experience is that leetcode problems are harder in general for a given level. I interviewed at Google and Facebook and the problems I got were "medium" level on Leetcode.

Given this dumbass question, no, no you shouldn't
