Preparation
Duration: 6 months
Topics: Data Structures and Algorithms, Git, Low-level design, Java, OOPS, DBMS.
Tip

Tip 1 : Keep the focus on the quality of the question and its various solutions rather than the number of questions solved for DSA.
Tip 2 : I would recommend enrolling on some courses for DSA to regulate your learning as I enrolled the DSA with Java from Coding Ninjas and practised over the LeetCode platform.
Tip 3 : Don't fear of rejection, always welcome the opportunity because if you get rejected you will definitely be a better person in professional as well as personal life than before attempting the interview.

Resume tip

Tip 1 : Keep your resume more specific to a particular domain rather than mentioning all the tech stacks you are aware of, it will make it easier for the recruiter to shortlist you for the opening.
Tip 2 : Keep your resume simple and short (1 page), try to mention specific words to explain your work in a project very well and then you can explain your role in the one on one interview.

First, I told the brute force approach to count the frequency of x with a time complexity O(N).
Then I told her that we can optimize this O(N) to some O(log(n)) using binary search. So here, we 1st find the occurrences of number x and then run the loop to match the value with the given number between left and right indexes, which reduces the time complexity to {O(log(n))+count}
Then I tho...

After I asked the HR about the 1st round verdict he replied me to get ready in 10 mins for the 2nd round as I have cleared the first round, but I remember I was travelling for some personal reasons on that day so I asked HR to reschedule my interview after 3-4 hours. So he scheduled my 2nd round at 3 PM on the same day( 5 Mar 2022), I confirmed the timing and my availability and the call were scheduled. This is the hiring manager interview in which I am going to join if I am selected.(luckily today I am working in thisteam)
