Many companies have started asking questions related to Concurrency and Parallellism in the interviews, while the resources and practice problems for these topics are limited. Even though Leetcode has a separate section for these, the number of problems to practice are very few.

I strongly feel Leetcode should add more problems in this section.

Interview experience where these were asked recently (feel free to add more in the comments):

• Linkedin
• Rubrik
• Goldman sachs
• Meesho
• Razorpay
• Grab
