Standard Chartered Software Developer Interview Questions, Process, and Tips

Round duration - 150 minutes
Round difficulty - Medium

For MCQ Round, we have 2 rounds:- 
1. Logical Reasoning (Window of 4 hours)
2. Mathematical Reasoning(Window of 4 hours)
The environment was fine. They gave an option of attempting a mock test in order to familiarize us with the environment

Logical Reasoning, in which there were 12 questions, and for each question we had a time limit of 75 seconds. There was a cut-off of 40 for the next round, and people who qualified were sent an e-mail with a link to continue with the process.

Numerical Reasoning, in my opinion, was the most challenging round. The questions were in a pair of 3 in which a table/bank statement was given and 3 questions were based on that. The questions were purely based on calculations and semi-subjective. The time given for the 1st question was 90 seconds and for the rest 2 questions, 75 seconds each

For Coding Round, 
120 minutes window(Test was of 90 minutes)
We have two questions
For the first question(30 Minutes)
For the second question(60 Minutes)
The tricky thing was we only had one attempt, i.e we were allowed to submit the solution only once.

Ans. 
Step 1 : We can solve this using recursion but it will be too slow
Step 2 : So to improve the complexity, we need to use memoization so that we will not recalculate the same step again and again
Step 3 : Recursion + Memoization = Dynamic Programming solution Passed all cases

The timing was around 1 pm and the whole interview went for about 40 minutes.
The interviewer first went through my resume and asked me to introduce myself. After my introduction, he asked me about my projects mentioned in the resume. In the introduction itself, I told him that I am interested in competitive programming and preparing for ICPC. He then asked me about my preparation for ICPC. He then asked me some questions from OOPS. I was then asked 1 simple CP problem. The interviewer also asked about situation-based problems. As I previously mentioned about Competitive Programming, he asked how this will help in adding value to the company.

Ans. 
Step 1 : To mark the presence of an element size of the array, n is added to the index position arr[i] corresponding to array element arr[i].
Step 2 : Before adding n, check if the value at index arr[i] is greater than or equal to n or not. If it is greater than or equal to, then this means that element arr[i] is repeating.
Step 3 : To avoid printing repeating elements multiple times, check if it is the first repetition ...read more
