- Q1. Find LCA of a binary tree, standard dsa medium problem
- Ans.
LCA of a binary tree is the lowest common ancestor of two nodes in the tree.
Traverse the tree from the root node to find the paths from root to the two given nodes.
Compare the paths to find the last common node, which is the LCA.
Use recursion to solve the problem efficiently.
Handle edge cases like if one of the nodes is the ancestor of the other.

- Q1. What are foreign keys
- Ans.
Foreign keys are columns in a database table that reference the primary key of another table, establishing a relationship between the two tables.
Foreign keys ensure referential integrity in a database by enforcing relationships between tables.
They help maintain data consistency by preventing actions that would violate the relationships between tables.
For example, in a database with tables for 'orders' and 'customers', ...
- Q2. Implement depth first search in tree
- Ans.
Depth first search in tree is implemented using recursion to explore each branch fully before moving to the next.
Start at the root node and recursively visit each child node before moving to the next sibling node.
Use a stack to keep track of nodes to visit, pushing children onto the stack before siblings.
Base case is when the current node is null or a leaf node, then backtrack to the parent node.

- Ans.
Yes, the 0/1 Knapsack problem can be solved using dynamic programming with a space complexity of not more than O(W).
Use a 1D array to store the maximum value that can be stolen for each weight capacity from 0 to W.
Iterate through each item and update the array based on whether including the item would increase the total value.
The final value in the array at index W will be the maximum value that can be stolen.
- Q3.

- Ans.
Given a directional string representing a route to a friend's house in an infinite grid, find the shortest lexicographically smallest route to reach the destination.
Iterate through the directional string and keep track of the movements in each direction (E, W, N, S).
Calculate the final position based on the movements and find the shortest lexicographically smallest route to reach that position.
Consider the constraints ...

Interview Preparation Tips
Experience: Interviews were driven to know the candidate better and their capabilities. They also didn’t waste much time asking students who they were sure not to recruit and conducting reasonably long interviews.
General Tips: Do’s :
1. Start preparing with the start of the summers.
2. Concentrate on your own preparation and not on what others are doing.
3. Keep the preparation time of HR to maximum 20 hours because HR accounts for just 20% weightage in your selection procedure.
4. Have patience.
5. Prepare every point written in the resume such that you are able to speak for at least 3 min on the subject. You might gain bonus points if you are aware of some latest developments or strategic changes in the field.
Don’ts :
1. Never bog down when you are either not shortlisted in the company who have been aiming for or when even after practice you are not getting the correct way.
2. Do not form very large groups for the preparation. Try making the preparation time that you spend with the group as efficient as possible with the least of bulla sessions.

Experience: GD was conducted for shortlisted candidates and candidates were divided into groups of 6 people.There were 3 topics and each topic was discussed for 2 minutes.No specific rules,like each person needs to speak,are to be followed during the GD.Anyone can initiate,intervene,etc. Finally we were asked to link all three topics and this discussion went on for another 2 minutes.
Round: HR Interview
Experience: Only a single round lasting about 40-45 minutes.There were only 4 people in the panel and technical as well as HR questions were asked. First I was asked to go through my own resume, “Introduce/Tell us about yourself?". E.g.:“Where have you shown leadership qualities?Have you led a
team?Size of team? What new initiatives did you take?”.Core questions starting form basics like “How does an airplane fly?” to specific questions about the different types of engines used in airplanes,their specifications, etc. were asked. HR questions were put up like"What was the most difficult decision in your life?" and grilled on my internship for 15-20 minutes which I did in Transocean. (Another oil field services company).
General Tips: You need to be very good in the basics of your
core courses and if you have done an internship in the oil industry,
you will definitely be grilled on that.Questions will be asked in quick succession.
Skill Tips: Highlight any intern in Oil industry or anything related to that in your resume.Any POR or any sport activity which shows your leadership qualities should me mentioned in your resume.
Skills: Leadership qualities, Athletic, Quick thinking, presence of mind

Experience: 10 candidates shortlisted through aptitude test (50 ques in 12 min, cut off was 50).
Duration: 12 minutes minutes
Total Questions: 50
Round: Technical Interview
Experience: 1st interview was technical with some general HR questions. I related the work done in internships to the work being done in the snapdeal company. I was asked if I had any other interview to which I replied flipkart. He then asked me why snapdeal and not flipkart. I had studied everything about the 2 companies and was thus able to defend my choice. Next he gave me some puzzles, I did all with little inputs from him. I was asked to wait for 2nd interview and not go to Flipkart GD but I went anyway.
Round: Technical Interview
Experience: This interview round was again technical. This time there were 2 panellists and they again gave me 4-5 puzzles, which I did successfully. I was asked to wait for a HR interview.
Round: HR Interview
Experience: The HR interview was just a formality, he explained me my responsibilities in the organization and made me a spot offer.
General Tips: 1. Pre placement preparation is very important. Begin early and try to distribute time to all the areas especially your shortcomings.
2. Try to remain calm and confident in the interview.
3. Do not cram up the answers to hr questions or puzzles.
4. There are plenty of companies with handsome compensation. Just give your best in preparations and interviews.

Interview Preparation Tips
Experience: An aptitude test which was followed by three rounds of technical interviews and finally the HR interview.
Round: HR Interview
Experience: Snapdeal offered placements for 5 students (3 from CS and 2 from IT).
General Tips: Be extremely well prepared for any company. Research about the company's profile extensively before the company's interview. HR panel always looks for candidates who are well aware of the company in order to measure the candidate's interest. Data structures are absolutely necessary for any company. Improve coding skills through frequent participation in competitive programming arena such as codeForces, codeChef, HackerEarth etc. "Software development job profile was offered to me.
Unnecessary and irrelevant questions are to be avoided. We should raise questions only if we have some genuine questions. However any question related to job profile or location preference could be raised. "
"It was very grueling and tiring at first but the sweet taste of placement makes it all worth it.
Placements are a turning point in everybody's career."
Skill Tips: Snapdeal is more focussed on Data structures and object oriented technology.
For data structures, online materials such as GeeksforGeeks are excellent and in case of OOPS concepts, stronghold in either C++ or java programming language is necessary.
