Tiger Analytics Interview Experience for Data Analyst (On-Campus)

Recently, I have been through the interview experience of Tiger Analytics Chennai and I would like to share my experience with everyone. Totally there were four rounds 1 written + 2 technical 

Every round was an elimination round.

Round-1(Aptitude and Technical questions): This round is a huge elimination round which contains(20 questions) MCQ’s on aptitude and some technical questions on OOPS, time complexity and algorithms.

Aptitude Syllabus:

• Probablity (most important)
• permutation and combination
• Work and time
• Geometry(straight line and circle ){3 to 4 questions were from this topic}  and some other topics not remember exactly .

only 13 members are qualified to the next round.

Round-2(Live coding round): everyone got a test link which conducted on hackerearth.com. There was 5 questions each questions have some marks from 20 to 100.

1. Greatest common divisor

   Determine the total number of natural numbers less than or equal to N such that the greatest common divisor of the selected and N is less than 3.

   while solving this question you should also consider time complexity. otherwise you probably get a TLE.

2. https://www.hackerearth.com/challenges/competitive/pycon-2020/algorithm/height-equality-8e0b29c7-1e5fe74d/> – Height equality
3. Farthest From zero

   You are given an integer array A of size N
   Your task is to print the farthest element from O. If there are multiple elements, print the number with the least value.

   I did not remember exactly that two questions. I was able to do only two out of these five questions.

The number of students qualified from this round is 4 out of 13. I was one of them.

Round-3(Some easy problem solving and Apti related to Data Analytics): Interviewer joined and started with tell me about yourself. she introduced herself then she started asking some problem solving. first questions was find missing number. she told me write the code for this problem. then she gave me some more problem and also some pseudo code that were easy. if anyone know basic then solve easily.

 After that she asked some probability questions 

1. The number of ways in which 5 boys and 4 girls sit around a circular table so that no two girls sit together is:
2. What is the probability of having 5th Sunday in the month of December.

After that she asked me some statics based question that was also easy. She also asked some scenario-based questions. but that were easy. it was 45 minutes round. Finally, next day morning the results were declared any 2 members were offered for Intern + FTE for Analyst role, and I was one of them.

Tips: 

• Be calm and think for answers, ask the interviewer for time they will definitely give you. If no idea finally ask for a hint(I suggest you this finally if no alternative is there)
• Try to keep only the concepts you are perfect in your resume.
• One should also have some basics problem solving skills.
