Twitter Interview Process

I applied at Twitter for the post of Software Engineer through an online application. I was interviewed at Twitter. There were a lot many rounds in the hiring process and I will try my best to explain each of those round below.

Round 1 - Telephonic Screening
I got a call from the recruiter after I applied. She covered all the resume based questions at the basic level and a brief introduction also took place. She told me more about the company and their requirements. Then there were some technical questions that covered the basics well.

Round 2 - Telephonic Interview
After the call from recruiter, I was called by the hiring manager. This was a longer interview as many questions were asked. The interviewer covered all the technical aspects a bit more in detail than the previous round. I was able to answer majority of the questions and the hiring manager was clearly impressed by me.

Round 3 - Second Telephonic Interview
I was called by a senior engineer who took the whole level to somewhere else. The questions were pretty difficult and if I would not have studied well, I would have been rejected right away. Luckily I spent much time in preparing and was able to perform decent (not great).
* After the telephonic interviews, I was called again by the recruiter who called me in for the onsite interview.

Round 4 - On-Site Interviews
Since there were about seven to eight interviews that took place on-site, it would not be feasible for me to write about every single one of them separately. So I would try to cover for them in general. All the interviews will last on an average for about half an hour or more. You will be flooded with all sort of technical questions in these interviews. Some of the questions that were asked:
Q1. Create an application which displays a word ladder between two strings.
Q2. If there are P lanes and Q cars in each lane and Cars[i][j] = (position of car, length of car), and if a frog desires to cross the road in one straight jump (vertically down), not bump into any car, write a function to conclude if he will be able to do it. You are given a frozen state of the road.
Q3. Reverse the order of words of a sentence in place.
Q4. Generate a random sentence using markov chains.

Other than technical questions, there will be a lot of cultural fit type questions. Please don't fake your responses or they will know about it. Also, many human resources based questions were asked. Some of the questions:
Q1. Why do you want to work for twitter?
Q2. What would you like to change about our product 'P'?
Q3. What type of manager would you like to work for?
Q4. How will you work under a team?

How to crack Twitter Interview

The overall hiring process at Twitter was really extremely comfortable and smooth. There were no glitches of any sort. The recruiter was so polite and placed enough information in me about the company. I can say the same for the hiring manager. Very polite and very efficient. Also, the scheduling is amazing and if you have that sort of time, you can finish off the entire process within a week.

There were many technical questions that were asked. To give you a faint idea, I have mentioned the kind of questions that were asked from me. But I would say that you will have to prepare hard if you want to be a part of this fabulous company. This is because the questions come from any direction and you must be prepared for that. I can't give specific pointers about anything as you might feel cheated if those pointers does not come true for you. There are about eight on-site interviews and thus you should prepare for the worst.

After your interviews, the recruiter will wait for the feedback of every interviewer and only then, you will be contacted and informed if you are hired or not. The package is negotiable and it all depends on what impression you generated in your interviews. So pull up your socks and prepare hard. All the best for preparations and the interviews.

Thanks Anmol for sharing the details of your interview.
