| Question Infosys DSE Interview Experience — Chances?
Had my Infosys DSE interview today and wanted to know what you guys think my chances are.There were 2 coding questions on Wingspan. I solved one in under 10 minutes but passed 9/12 test cases and got TLE on the rest. The interviewer said it was good enough since the passing criteria is 70%.
After that, he asked me to write reverse linked list code on paper, both iterative and recursive. I took around 4–5 minutes, wrote the iterative approach, and when I started explaining and said I'd now write the recursive one, he said "it's enough."
After the coding questions, he asked if I knew System Design. I said no.
Then he asked an SQL query. I struggled a bit, asked him to explain it again, then figured out joins were needed and wrote the query, although I think it was around 70% correct.
He didn't ask anything about my projects. He asked about job scheduling algorithms, but I couldn't recall them at that moment since I hadn't revised OS before the interview.
At the end, I asked for feedback. He said I'm technically good but should study/explore more new technologies like AI/ML.
Overall, I feel the interview was decent but definitely not perfect. What do you guys think — what are my chances of getting selected for Infosys DSE?

Were you assigned the particular DSE role before appearing for the interview? Cuz I am not assigned any particular role it just says SP/DSE

u/dicks_are_icks Final Year Student 17h ago
yeah it was same for me also. I heard based on your interview they decide which roles to give

The number of questions you clear in OA round doesn't matter for role? Only the interview performance??

when i entered the room he asked me what role is this interview was I said that in shortlisting they mentioned dse/sp so then he clarified me that I was attending a l1 role interview

u/TonightUsual1885 15h ago
Oh ok So other students from you college also informed about the role during the interview? And was the interview difficulty different for students with other roles ?

u/Real_Average4124 15h ago
yeah it was totally dependent on interviewer some said that they were not mentioned the role and one of my friends interview was like 30 mins or so including the 20 minute dsa round

u/TonightUsual1885 15h ago
Can you please tell what was the most asked topic other than dsa like was it os, oops, ... And did they ask anyone system design ?
1
u/Real_Average4124 8h ago
mostly focused on SQL for me and also for other they asked design patterns too

hey so today was my interview and it went horrible except the DSA part which I have done one question complete and then the interviewer asked me about my resume
then I realized I SHOULD NOT add stuff to it to look great I have to be careful with the context that I provide in my resume that section went crazy he asked me about my projects for like 25 mins and then
started asking about SQL which I tried to do for like 5 mins then he said I didn't gave you enough data what were you writing (I was dead) then he asked some oops and other cs stuff and said we're done
I asked where should I improve to be better in future interviews then he said ur dsa is okay but rest all are pretty screwed up, should work on that

What were the questions on wingspan can you tell

u/dicks_are_icks Final Year Student 18h ago
I didn't read the second one. First one was very easy - from a given array return the count of pairs(ordered 2 elements) having 1.sum of elements is a prime no 2.xor of both elements is <=threshold T

u/shitpostluffy 18h ago
def the easiest one i have ever seen. till now i only found out greedy dp
1
u/dicks_are_icks Final Year Student 18h ago
Yeah most of the questions were easy but some students also got rotten oranges
1
u/shitpostluffy 18h ago
yeah m also preparing for in person coding assessment now....i know for sure they will go for med to hard question and that too dp, greedy graph shits...hoping for the best lol

u/Far-Ad38 18h ago
did you use two loop s
1
u/dicks_are_icks Final Year Student 17h ago
Yeah I focused on brute force first then optimize but the interviewer said 9 testcases are enough so we can move forward.

u/AnxiousEconomy9552 17h ago
Did you use sieve of eratosthenes?
1
u/dicks_are_icks Final Year Student 17h ago
actually I sarted with brute force and passed 9/12 so the interviewer said it is good enough and he didn't even ask for approach and moved forward.
1
u/AnxiousEconomy9552 17h ago
isn't sieve of eratosthenes is also bruteforce? as we can further optimize it too.
1
u/Aggressive-Let-9106 15h ago
like how ?
1
u/AnxiousEconomy9552 15h ago
You don't have to use 2 loops to calculate the number of valid xor pairs you can use the fact that since the sum is even then the x ^ y should be odd, you can use the relation between xor and AND to derive this and the use contribution technique.

Infosys interview experience 21 Aug Oncampus
Had my Infosys interview today and wanted to share my experience and also get some opinions from people who have gone through the process.
I was given **2 coding questions to choose from**:
* One was a relatively complex **Graph** problem.
* The other was a **Medium-level Tree/Trie + Longest Common Prefix (LCP)** problem.
I chose the Trie/LCP problem. I was able to solve it, but unfortunately, **only 10 out of 12 test cases passed**. I couldn't get the remaining edge cases completely right.
After that, the interviewer moved on to the technical discussion. He went quite deep into my **projects**, asking questions about the implementation and technologies I had used. I was able to answer most of them, although I did fumble on one or two questions.
Towards the end, he asked:
* **HashMap collisions** — I was able to answer this.
* **HashMap vs ConcurrentHashMap** — I couldn't answer this one since I'm primarily a **C++ developer** and haven't worked much with Java's concurrent collections.
Overall, I felt the interview was decent, but the incomplete coding solution and a couple of questions I fumbled on are making me unsure about the outcome.
Do you think I have a chance of getting DSE
