I was interviewed on-campus at IIT Kharagpur for Data Analyst role at American Express
Interview Process
Resume Shortlist Test Technical Interview Puzzle Interview
Round 1

Resume Shortlist

Interview Experience
My resume had a couple of projects and a paper publication added to it, which was a part of my second year intern at TCS Innovation Labs.
Interview Tips
I believe that the resume shortlist to appear for the test is just a formality and not a big deal to get through. Most of the students are allowed to appear for the test which is where, the main shortlisting occurs.
Although, the company does cut off people from certain departments. For example, none of the Agriculture and food engineering students were shortlisted for appearing for the test.
Also, from what I have heard, the company runs resumes through a program to take out the shortlist. Hence, certain key words such as "Scholar" or "Conference" may get you a good chance to get through the shortlisting.
Round 2

Test

Test Sections
  • Section 1: Analytical
Interview Experience
The test is mainly quant based and how fast you can think and rationalize. They expect excellent speed; they ask you 20 questions to be answered in 30 minutes.
Interview Tips
Normally, if a student is asked to appear for this right after his JEE examination, he would be able to get through it easily. But since our analytical thinking goes way down once we actually get in, it has to be worked upon again. I'd suggest you to solve all the quant questions of any CAT preparatory book for the American Express test. The test questions are quite similar to those that the CAT students prepare for.
Round 3

Technical Interview

Interview Experience
In general, the American Express interviews are considered to be pretty peaceful compared to the interviews of other companies. I was just asked about my work at TCS Innovation Labs and the paper I would be publishing based on that work and the courses I have done in Data Analytics and what all do I know in it. They do not test the knowledge you say you possess.
Interview Tips
While I was preparing for my interview, I was told to read about Amex and its products. Secondly, and most importantly, I was aksed to read a lot about credit card frauds and suggest ways of preventing that. Even during my time, a lot of people were asked about this and judged severely on that. This is a must must if you would be appearing for its interview.

Also, you would do well if you are able to connect with the interviewer. For instance, if both of you have been a part of the same inter IIT or have the same tastes, etc.

Also, the interviews are that peaceful that you are able to direct the interview in your favour. There are certain parts of your CV that you can easily talk about and certain parts that you would want to avoid. If you are able to think on your feet, it is easy to re direct the interview in your favour and the things that you would like to talk about; in my case, it was my work at TCS.
Round 4

Puzzle Interview

Interview Experience
The main decision whether you have to be taken in or not is decided in your first round of interview after which, the puzzle interview is just a formality and to find out whether you are able to think on your feet or not. Not a big deal, pretty easy.
Interview Tips
Nothing to be worried about, the puzzles asked are pretty easy and most probably, you would have already heard them if you have a nag of solving puzzles.
Skills

Skills Tested

Skill Tips
You should be able to code efficiently. Knowledge in Python and SQL is a big plus.<br /> Also, I had done a course on Coursera called "Machine Learning" of Stanford University. Today, the company does not expect a lot of knowledge in Data Analytics from students which is why this course gave me the edge I needed to get through the interview. It's a pretty easy course and not very demanding. I would recommend this if you want to find out even whether you'd be interested in Data Analytics or not.<br /> I was asked about the things I know and whether I have ever implemented them.
Resources

Preparation materials

Books
  • CAT Data Interpretation By Arun Sharma,
  • Data Interpretation And Logical Reasoning By Arun Sharm,
Courses
  • Machine Learning - Coursera Course,
General Tips
Do not worry or stress yourself much. The interview is pretty easy if you have an edge in the skills that the company wants. I had started studying Data Analytics in my second year summer vacations, just 1 hour a day for hardly about a month. Which gave me enough of an edge. The main hurdle lies in getting through the test round where about 300 people are simply cut off.
Motivation for applying
American Express is known to have a good working culture and is currently the third best company to work for in India. The internship stipend is largest compared to any other company in India along with accommodation and travel. The company has a well structured internship program and also has good challenging work to offer.
Funny Moments
After the test, I was not shortlisted for the interview round.. Which broke my heart.

Just after the presentation, I walked up to the person presenting and handed him a hard copy of my resume asking him to at least give me a shot at the interview if they think my profile is good enough.

I believe that this was a turning point of this entire experience. I believe, at that moment itself, I gained their favour to take me in. Which is probably why my interview was peaceful, which is probably why I could get through even though my interview was the last among a bunch of 25 students..

Resume Shortlist

Interview Experience
Sent resume to an HR through Linkedin and got the call for interview
Round 2

Technical Interview

Interview Experience
Had 3 rounds of technical interviews with Product Owner, Product Manager and VP Product. Most of the questions were related to maths, statistics and a few on machine learning. Even though I did not have much background on these, I was asked to give my inputs and try to find a solution. We discussed recommendation engines for Quora, Linkedin and e-commerce websites. Then they asked me how can we remove the bias that comes in the practo ratings of the doctors due to feedback from various channels. How can we identify if the customer is booking an appointment by looking at reviews or ratings? How can we identify spam reviews before publishing them? How can we build a product which can help users write a better quality review? Most of the questions were related to data science and how we can improve the products using data. The data analyst role for which I was being interviewed, was a first of its kind role in Practo. The JD was to basically work with the product team and help them in improving products, building new features etc. using data science/ data analytics.
Motivation for applying
being the leader of the healthcare industry, high growth startup, opportunity to solve interesting problems using data

Interview Process
Test Technical Interview Technical Interview HR Interview
Round 1

Test

Duration
60 Minutes
No. of Questions
40 questions
Interview Experience
The questions were of medium to high difficulty. What set this test apart was the fact that each question had different weightage ranging from 0.5 to 3 marks per question. Time was a major factor. So my strategy was to attempt all the 1 and 1.5 marks questions which constitute the major chunk of the paper in around 40 minutes and spend the remaining 20 minutes for the 2 and 3 mark questions. I did not even bother reading the 0.5 mark questions. The 2 and 3 mark questions were difficult and those will differentiate you from others. 1600 students wrote the test and only 86 got shortlisted for the next round.
Round 2

Technical Interview

Interview Experience
I was asked to write a C program to print the Fibonacci sequence and a basic SQL query. Apart from this I was asked a puzzle and other questions related to my resume. Out of the 86, only 26 students were called for the next round which again was a technical interview.
Round 3

Technical Interview

Interview Experience
This was similar to the first technical interview. I had to write a C program to print the prime numbers between 1 and 100 and a puzzle was asked again. Apart from this a guesstimate to find the number of cars between 2 places was asked and a scenario based question too was asked. These were followed by resume related questions.
Round 4

HR Interview

Interview Experience
All the 26 students who attended the second technical round were allowed to attend HR round as well. This was just for 4 - 5 minutes. I was asked about my family background and why I should be hired. My fondest memories from school days were asked too. Finally offer letter was given to 10 students out of the 1600 who wrote the test :P
General Tips
Just keep a calm head and attempt the questions. Ask for time to think if you are not able to answer the questions immediately. Be bold and confident. That is sufficient :)
