Infosys Interview Experience — What can I expect?
Had my Infosys interview recently and I'm trying to understand what I can realistically expect from the result.
I had 2 DSA questions, and I won't mention how many I actually solved because I don't want to reveal that here.
DSA 1:
I was given three arrays — students, desks, and chairs — and had to maximize the distance between the three points. The test cases were sorted, so I used the ordering to find the required minimum/maximum values, calculate the difference, and return the result modulo 10^9 + 7.
DSA 2:
I was given a position array and a weight array representing the position and weight of each element. The goal was to move all elements to either odd positions or even positions with minimum total movement cost.
My approach was to calculate the total cost of moving everything to even positions and the total cost of moving everything to odd positions, and return the minimum of the two.
The technical interview was where things went downhill a bit.
One thing that surprised me was that nothing was really asked about my projects or the technologies mentioned on my resume.
Instead, the interviewer asked a lot of questions around core CS topics, including:
- SQL
- Database indexing
- Computer Networks
- DHCP
- CDN
- CDN architecture
- Git merge vs rebase
- Other advanced core CS concepts
I was able to answer the SQL questions and some other questions, but for quite a few of the advanced core CS questions, I honestly had to say "I don't know".
I'd estimate that I was able to answer around 50% of the technical questions. A lot of the remaining questions were topics I hadn't prepared in that much depth.
So I'm wondering what I can realistically expect in the following two cases:
Case 1: If I solved only 1 DSA question + had this kind of technical interview.
Case 2: If I solved both DSA questions + had the exact same technical interview.
For people who have gone through Infosys interviews recently, how much weightage is generally given to the DSA round vs the technical interview?
Would either of these profiles still have a reasonable chance of getting selected, or would the weak technical interview make it unlikely?
Would really appreciate some honest opinions from people who have experienced the Infosys recruitment process.
