I got jobs at Morgan Stanley (java dev) contract via Synechron and Amazon because of this basicsStrong course. For Amazon, obviously leetcode is extra, but these design patterns during Low Level system design round is useful!!!

said basic java knowledge is enough but with basic java it is very difficult to understand the content in this course .initially didn't understand then i started googling for many things.
By Ramakanth Naidu Kusu on 5/12/2023
Content was excellent, thanks for your all your efforts. But already lot of students are asked about resources such as PPT slides and programs. Even though programs are sample one's, but that are very use full for students to go through quickly and understand implementation in case of revision. Hope you understand and please share PPT slides and all programs your written as part of this course. Please share it ASAP.
By Moulana on 2/27/2023

The content is great but the educator is not able to explain the concepts in a clear manner. Getting more confused after going through the video content. Just using the downloadable part for reference.
By Roshan on 12/28/2020
The course is really worth for preparing an interview. It covers all topics. But the source code is not available for practice. Checking with Instructor whether it can be added in the course.
By Rahul Kumar on 12/22/2020
