Round: Technical Interview
Experience: Online Skype Round

Round: Technical + HR Interview
Experience: This was the worst round because it was the skype round and there was communication problem. The interview started with summer intern project discussion and I required
to draw some diagrams to explain him and it was really difficult to explain him through the poor communication but he somehow got the idea of project.
He asked there are 2 type of transactions in bank credit and debit, He asked how will you model the total amount of money available at bank..(Threading question based
on syncronisation) he asked me to do in JAVA but I told him that I know c++ only, he told me to build in c++ but he wasn't seems to be satistfied fully however he said
its alright.
Then he gave me real confusing problem ---> we are given a huge data of points in 2D points and this point can be floating points. Now you are given queries where you are given a rectangle and you need to output the
all the points inside that rectangle.I proceeded by making buckets in x-axis and then for each bucket along x axis,(I further bucketed along the y-axis, he also helped me a bit in that. )
Then he told he was done and if I had any question- I asked how the team is decided and what is general strength of team and how to switch(15 min discussion.)
I thought that I did fine but may be CV and branch was the weak point as directi is very selective but very few reached the final round, they selected only 2 students but
really good company to work in
