I've already been working at it for a few weeks now, but I want to swallow my pride and stay up-to-date on interview skills (thankfully I'm safely employed but want to make sure I'm prepared if I need to be.) I do 2-3 leetcode problems a day and at least try to fully understand each line when comparing against the answer. I'm still pretty bad at it but instead of being terrified/anxious in the future I'd like to be confident that I at least can do my best. And my best is being prepared as opposed to just hoping I magically intuit a whiteboard problem out of thin air.
