  • Really pumped up with all the points and questions covered in this Mock interview. Spring Boot, Microservices, Basics of Hibernate, Exchange, Circuit Breaker and what not. Please do make some more mock interview videos on Advanced Java and Core Java as well. If I had the authority, I would do 1000 likes but will do at the most shares that I can do. Such content is never available for free, unless its "Abhilash from Selenium Express" ❤

  • Great session. @20.22 REST API principle is not to hold state at API level. The reason is when you have scalable architecture, you have many instances of the same application. Requests are passed in Round Robin fashion so we are not very certain that request will always hit the same machine. Sticky sessions are used for sending same request to the same machine. It has nothing to do with microservices.

  • Hi, about 51:30, isn't bulkhead pattern better for this type of situations? I mean I tought that rate limitter is more for ddos attacks, but in this case bulkhead pattern is created for those kind of situations when one endpoint is slowing the whole microservice so others will work anyway after implementing bulkhead pattern. Of course I may be wrong so please explain why rate limitter is better in this case :). Except that, great video, I watched whole series and your videos are better than others because video quality is good, your english is easy to understand, questions are not typical, and everything is explained very well

I listened to questions carefully and answered myself first. I noted every topic and researched it even more. And I learnt so many things. I was fully prepared. Then the day came. I was in interview, I answered almost all of questions, it went similar to this video. It was really good. But after a day I got a "Thanks for your interest but Unfortunately...." email.😂 I don't know man, they don't even tell the rejection reason.
