Interview Preparation Tips
Do practice a lot of data structures questions as mostly questions in interviews are based on them. Also, do prepare for projects mentioned in your resume and skills which you have mentioned. Coding ninjas has a big hand in making my interview clear as I have taken a course from the coding Ninjas which helped me a lot to make my concepts clear.
Application resume tips for other job seekersKeep it short and crisp. Go through it properly before the interview. Make sure that you haven't put anything in it that can cause you problems during the interview.

- Q1. Can string class be extended
- Ans.
Yes, the string class can be extended in most programming languages.
Inheritance can be used to extend the functionality of the string class.

Extending the string class allows for customization and adding specific functionality to strings.
Example: In Python, the string class can be extended by creating a new class ...

- Q3. How does hash map works
- Ans.
A hash map is a data structure that uses a hash function to map keys to values.
Hash map stores key-value pairs
It uses a hash function to compute an index for each key
Collisions can occur when two keys hash to the same index
Hash maps provide fast access to values based on their keys
- Q4. Difference between string buffer and string builder
- Ans.
StringBuffer and StringBuilder are both used to manipulate strings, but StringBuffer is thread-safe while StringBuilder is not.
StringBuffer is synchronized, making it safe for use in multi-threaded environments.
StringBuilder is not synchronized, making it faster but not thread-safe.
StringBuffer is preferred when multiple threads are involved, while StringBuilder is preferred for single-threaded scenarios.
Both classes p...

TECHNICAL INTERVIEW: (pls list the questions asked in all the rounds)
26 shortlisted after apti (14 directly for interviews & 12 had one more technical on paper test...mentioned above)
der wer min 2 technical rounds for each of them...max were 5
- You are given course dependencies
A->B,C
B->D
C->A
D->nothing
The above dependencies mean...if you want to take course A...you should take courses B and C first....To take B,Course D must be taken first....D is an independent course and can be taken without any prior requirements.
Now you are told these dependencies.Come up with an appropriate data structure to represent these dependencies.Then write a code that finds out all the courses that the student can take up...in this case the student can first take course D because its independent.Now that course D has been taken he can next take up B as it depends on B alone...But the courses A and C can never be taken because they depend on each other...So here all the courses that can be taken are B and D.
After i wrote the code....he asked for all possible test cases
-Given an array of length N....It can be filled with nos. only from 1 to N....find which nos are repeated in the array
-Given pointers to two nodes in a binary tree....find their least common ancestor...each node has pointer to only the parent node...not the left and right child..
-In a binary tree(Not necessarily a BST)...suppose the weight of any node is defined as the product of the key value of the node and the level of the node(Root at level 1)...find the node with maximum weight in the binary tree
-A sorted array of size n is right circularly rotated k times and this rotated array is given to you as input...Find out the value of k in log n time .
-There are some processes running at time T....and there are processes running at time T+30.
You have to find out
1)Which processes died at time T+30,which were alive at time T
2)Which are the new processes at time T+30,which were not there at time T
3)Which are the processes that were there at time T and are still running at time T+30
What data structure will you use to represent the process lists and write code to find out the answers to the 3 questions above
-Given a binary search tree...and a target sum...starting at the root...which all paths add up to the target sum?...if there are multiple paths....return the path with least no. of nodes.

Interview Preparation Tips
Experience: The written test was quite similar to the typical CAT pattern. It contained sections on Reading Comprehension, Data Interpretation and Mathematics.
Round: Technical + HR Interview
Experience: There were 2 interviewers in the first interview, one was a technical guy and the other was from HR. They asked me a few very simple puzzles, a few basic programming questions (swapping the value of two variables etc.), questions related to the development cycle of software products. The HR guy asked stuff like what do you want to achieve in life? Strengths, weaknesses etc.
Round: Case Study Interview
Experience: The third interview was the most important one (and I guess that was the deciding interview). The interviewer started with questions like why finance? Which companies are you sitting for? Then he gave me a case study:

College Name: Acropolis institute of technology and research
Interview Preparation Tips
Experience: The test was for two and half hours where 1 hour was for general aptitude, 1 hr was for coding aptitude(either on java or C or C++as you choose) and 1/2 an hour for two coding questions.
Round: Technical Interview
Experience: In technical round they asked puzzles, aptitude questions and basic C coding. I was asked to write the code for two questions(one was on sort and search) and was asked the logic of two questions.They asked basics of linked lists, stacks, queues. Infact they were not very interested in the syntax and were pressing on the logic
General Tips: Being a non software branch students is not at all a problem. The company took 4 interns where 3 were from core branches. The fact that we had to work in JAVA and most of us didn't know JAVA, the company only looks for aptitude and ability to learn. So if you don't know anything, tell frankly that you don't know that part, rather than guessing. Be thorough with what you know and confidentially answer all the questions.
Also do not be tensed and take things lightly, if the interviewer is joking. Be candid.
Skill Tips: Learn basics of coding from books . Aptitude can be done from sites likes geeks for geeks, etc. The level of aptitude is not very high and infact the coding aptitude is also theoretical and does not involve in depth knowledge.
