Teradata Interview Experience | Set 3 (On-Campus)
Recently, TeraData visited our campus for both developer and test developer profiles. I have been shortlisted for developer profile.
Round 1 : Written Test
- 20 MCQs in a time limit of 40 mins. Questions were from DS, OS, Computer Organisation, Recursion, C.
- The level of the questions was medium to hard. Conceptual clarity is a must to crack this round. Only 4 candidates were shortlisted for the second round.
Round 2 : Technical Round:2 hours
Purely based on C,data structures and algorithms
- Given two sorted strings,of length m+n and n, merge them into a single sorted string of length m+n in place.
- Run length encoding. Take care of the worst case when each character is repeated only once.
- Mirror of a binary tree
- Design a stack data structure that allows push(key) pop() and max() in O(1). Efficient usage of space was required.
- Search in a row and column sorted matrix
- Root to leaf path equal to the given sum.
- Given an array find it an element that can be represented as subset sum of the array.
- Declaration of some complex function pointers.
Round 3 : Technical 2 hours
char* s1="first" char* s2="Second" char* a1=s1; char* a2=s2; call and define a procedure swap( ?,?) where '?'=any type of parameter u want such that s1="first",s2="Second",a1="Second",a2="first"
Lots of discussion on stack area segment,heap segment,and read only area segments.
- Recursive and iterative fibonacci series with exact complexities. Find nth fibonacci number . Fortunately gave it in O(1)
- char str1=”First”
char str2=”Second”;What does the following code do
while (*str++ = *str2++); str1 = 'X'; printf("%s", str1);
- MultiThreading concepts
- Semaphore programming
- User level and kernel level threads
- What is NULL. Internal details of the same
Third Round: HR + Technical : 1 hour
- Write code that returns true if a matrix is a subset of another matrix
- Tell me about yourself
- Why should i hire you?
- What if you dont get to learn new things from the company?
- What do you expect from the company?
- Discussion on projects
- Discussion on articles that I have contributed on for GeeksforGeeks.
Final Round: HR:1 hour
- Introduce yourself
- How did you overcome some serious problem of yours?
- Why did you work as an intern for a company that paid you nothing!
- What is so unique about you?
- What is your plan after 2 years from now.
- Would you want to work for 24hrs a day for the company.
- What do you do in your free time?
- Any questions you want to ask?
- Be honest. Don’t fake anything.
- Enjoy the interaction to the maximum.
- Interviewers are really friendly and help you to get the solution
- Don’t give up while solving a problem. Before writing the code, get all the details without any ambiguity from the interviewer
- Interviews are quite time taking. Be energetic and patient enough for the entire process.
- Last but not the least, work hard and prepare well before.
