One coding question medium level.
The second was a puzzle. I wasn’t familiar with this puzzle at that time. So interviewer saw all my thinking processes.
puzzle was:
We have two water jugs, one measures 4 Gallons (4G) while the other measure 9 Gallons (9G). But there is no measuring label mentioned on either of these two jugs i.e. we cannot know the exact amount filled in the jug. Now, assuming there is an infinite amount of water supply, can we measure all 1G, 2G, 3G…….. upto 9G using these unmarked jugs.
Hint: We can empty the jugs, and transfer water from one jug to other.
Then the interviewer asked about my project like what is the concept of the project, technologies used, etc.

Interview Preparation Tips
Tip 1 : It is important to practice coding consistently because it is what enables you to solve interview-questions in the stipulated time. But before this, it is even important to have a clear understanding of all the data-structures, so that they can be easily implemented as and when required to solve a problem.
Tip 2 : They do not judge you upon the number of internships you have done or the number of projects you have made. A single,good-quality project is sufficient, provided you have in-depth knowledge about it.
Tip 3 : Practise topic-wise questions, participate in lots of coding contests, watch lots of Youtube solutions even after you could solve a question, because you may find a different approach that is efficient than yours,
Tip 1 : Keep your resume short and clear. Mention your projects and internships with a brief description and year of completion.
Tip 2 : Be very honest and figure out only those things in your resume that you really know.
