Solved LeetCode Problems More Than 300

I changed the job last year. I heard that there is coding interview in the company’s interview. So, I studied algorithms and practices solving coding problems at LeetCode.

Level up your coding skills and quickly land a job. This is the best place to expand your knowledge and get prepared for your next interview.
LeetCode - The World's Leading Online Programming Learning Platform -

I have solved LeetCode coding problems even if after job change. Then now number of solved problems is 331! Number of Easy, Medium and Hard questions is following:

Easy : 204 / 461
Medium : 113 / 921
Hard : 14 / 373

Actually after job change I have solved almost Easy problems though… By the way, after job change I just solve problems in order. But, before job change, I solved problems on the following Web sites. Excuse me, first one is Japanese Web site.

This section dives deep into practical tips for specific topics of algorithms and data structures which appear frequently in coding questions. Many algorithm questions involve techniques that can be applied to questions of similar nature. The more techniques you have in your arsenal, the higher the chances of passing the interview. They may lead you to discover corner cases you might have missed out or even lead you towards the optimal approach!

I follow the following steps to be able to solve similar problems at interview.

Reading Tech Interview Handbook and solving problems on that site.

Now I can solve problems not on those Web sites for 1 ~ 5 min for Easy, 15 ~ 30 min for Medium problems. Sometimes still I can’t solve Medium problem though… At screening, I could solve a coding problem immediately because of study using LeetCode.
