Selected Interview preparation journey
Preparation
Duration: 2 months
Topics: Data Structure and algorithms, DBMS, System Design, Core and advanced Java, Computer Networks (not much), Operating Systems
Tip 1 : Make you Data Structure and algorithms , Problem solving strong ( use to do some dsa problems on code studio and leetcode daily.
Tip 2 : Practiced Quality questions and mostly asked questions list available on codestudio( used company tags and topic tags) as quality matters more than quantity of questions .
Tip 3 : Give mock interviews, this really helped me as it gives you clearity and builds confidence.
Tip 4 : Read respective company’s interview experiences available on codestudio and other websites before going to actual interview, as this gives you idea about level of interviews and you can prepare beforehand.
Tip 5 : after solving dsa problem .Try to look in discussion section too as you can get more optimised or more efficient approach used by others to solve the problem.
Tip 6 : Prepare important concepts from Operating system,DBMS,System design too as that might also be asked.
Tip 7 : Do atleast 2 quality projects.
Not a Tip But : Lot of quality content available online, whenever felt like stuck with some concepts take help from senior or colleagues ( I use to watch coding ninja shorts by parikh jain whenever felt demotivated or stuck with concepts)

1. Remove Consecutive Duplicates From String
Moderate
22m average time
0/80
Asked in companies
You are given a string 'STR' consisting of lower and upper case characters. You need to remove the consecutive duplicates characters, and return the new string.
Note :
You don't have to print anything, it has already been taken care of. Just implement the given function.
Problem approach
It is a simple string question, that can be solved by recursive and iterative. The idea is to check whether the current character is equal to the next character. If the current character is equal to the next character, we will ignore it; when it is not equal, we will add it to our final string.It can be also solved with help of Hashset but that will need extra space.
2. Valid Parentheses
Easy
10m average time
80% success
0/40
Asked in companies
You're given a string 'S' consisting of "{", "}", "(", ")", "[" and "]" .
Return true if the given string 'S' is balanced, else return false.
For example:
'S' = "{}()".
There is always an opening brace before a closing brace i.e. '{' before '}', '(' before ').
So the 'S' is Balanced.
Problem approach
It is standard stack problem which can be solved using stack. Traverse the Expression string and keep pushing characters for open braces and if the current character is a closing bracket (‘)’ or ‘}’ or ‘]’) then pop from the stack and if the popped character is the matching starting bracket then fine else brackets are not balanced. After complete traversal, if there is some starting bracket left in the stack , then the expression is not balanced.
