Problem of the day
Tip 1 : Practice question from every section (Arrays, String, Data Structures)
Tip 2 : Practice question that required you to write test cases for a problem (as they judge you on your practical implementation)
Tip 3 : Practice low level designing questions (it indirectly helps you to write test cases )
Tip 4 : Choose your favorite Data Structure and practice well on it (as this is the most commonly asked question)
Tip 1 : Have at least three projects in your resume (Include only those which you can explain and demonstrate)
Tip 2 : Include a column of "Position of Responsibility" in addition to your work experience and technicalities (it is impactful as it shows your extra activities apart from your regular curriculum)
It was a coding round only consisting of three questions.
Question 1: It was quite an easy question from an array and can be solved in 5 -7 minutes
Question 2: It was a question related to a binary tree
Question 2: It was again a question of Data Structure
The question seems tough if you don't have proper knowledge or practice of Data Structure.
The interview started with the introduction of both. After that, he asked about the OOPS concept - inheritance, polymorphism, abstraction, and so on. Then, he moved onto coding questions that were easy ones but you have to optimize the code in terms of time complexity. Questions were related to String, Array, HashMap. After then, he asked about the concept of DBMS and a brief discussion of some of the concepts like primary key, Foreign key, and join -left, right, full, and so on.
Started with the introduction.
Then there were two-three coding questions.
Some OS and DBMS concepts were asked.
Questions related to testing were also included.
This was quite a tough round that can be cleared only by practice and understanding the problem. They asked about the profile first, then questions related to testing, SDLC, and so on. And then, I was asked to write test cases for two to three problems. Writing a test case was a task in this round. The interview was a senior testing engineer and was very friendly and helpful also and answered all my queries related to work.
