Interview Preparation Tips
Experience: There were questions based on probability, algorithms and graphs. Probability questions were simple. Algorithms portion was mainly on different sorting algorithms and their runtime. Graphs on graph asked about complexity, number of graphs possible, etc. Based on the scores, a shortlist was prepared for campus interviews.
Tips: Solving puzzles from -----/ and "Fifty Challenging Problems In Probability With Solutions" is good enough preparation for any question asked on probability during placement tests. For algorithms, a data structure course done in my college was helpful.
Duration: 30 minutes
Total Questions: 20
Round: Technical Interview
Experience: I was asked to explain my projects. After that, I was asked questions on PCA, SVM, KNN, linear regression, logistic regression, entropy, information gain, decision trees. The interviewer asked for equations in all topics.
Tips: Remember details about every aspect of your project. Even minor details like which features you extracted, why you chose certain classifier, etc were asked.
Round: Technical Interview
Experience: The interviewer asked me to explain about something innovative I had done in my projects. Then he asked a guesstimate question - Estimate the number of trees and plants in a city. This was followed by another guesstimate - How would you estimate the rate of growth of trees and plants if you have data only from the present. (no past or future statistics can be used)
Tips: Practice guesstimates as done for case interviews. Practice presenting your projects in an interesting manner with your friends. Ask your friends to ask you questions about your projects. Since they have heard about your project for the first time, they may ask you questions which you never thought of. This should be sufficient to get past the interviews for Xerox Research - Budding Scientist profile.
Skills: Algorithms And DataStructures, Guesstimate Skills, Machine Learning

I applied via Campus Placement and was interviewed in Dec 2016. There was 1 interview round.
Interview Questionnaire
2 Questions
- Q1. An MST is constructed for a very large graph. Now, one of the edges, in the graph, has its weight altered (either increased or decreased). Now obtain the MST for the new graph using the old graphs MST and ...
- Ans.
To obtain the MST for the new graph, we can use the old graph's MST as a starting point and update it based on the altered edge's weight.
Start with the old graph's MST
Remove the edge with the altered weight from the MST
Add the altered edge to the new graph
Run a minimum spanning tree algorithm on the new graph to obtain the updated MST
- Q2. Graph Theory : Obtain the number of tournaments with 'N' nodes. Now define a transitive tournament as one where any three nodes (i,j,k) can be arranged in such a way that i->j->k and i->k. Define sub-tourn...
- Ans.
The aim is to find an upper bound for the minimum number of nodes in a maximal transitive sub-tournament.
A transitive tournament is one where any three nodes can be arranged in a way that satisfies the transitive property.
A sub-tournament is an induced graph on a subset of nodes from the original tournament.
Every tournament with N nodes contains a transitive sub-tournament of size 2 (a directed edge).
The goal is to fin...
Interview Preparation Tips
Experience: I got stuck in the question as I wasn't able to approach this question. The interviewer helped me out by giving me the following two clues.
1. Two properties of MST : Cycle Property and Min-Cut Property.
2. 4 cases : (modified edge in old MST)*(weight increased or decreased) -> I eliminated two cases as it would return the old MST. Only 10 and 01 need to be considered.
Tips: Requires Graph Theory(Min Spanning Tree algorithm, Min Spanning Tree properties etc.)
Round: Technical Interview
Experience: I had no idea to approach this problem.
I decided to first come up with an algorithm to obtain the maximal transitive sub-tournament given a tournament.
The interviewer then told me to see if I can upper bound the minimum out-degree in a tournament.
After this, the solution was to upper bound the minimum size of the transitive sub-tournament.
HINT : Use the fact that a tournament contains N_choose_2 number of edges for part II.
Tips: Requires very little graph theory. More thinking based, proof oriented. I had to prove every claim I made.
Skills: Graph Theory, Logical And Structured Thinking, Proving Abilitites
