I applied via Recruitment Consulltant and was interviewed in Oct 2024. There was 1 interview round.
Understanding IR and NMR values helps in identifying possible products of reactions in chemistry.
IR values can help identify functional groups present in a molecule
NMR values can help determine the structure of a molecule by showing the connectivity of atoms
Possible products of reactions can be predicted by analyzing the changes in IR and NMR spectra
For example, a reaction between an alcohol and a carboxylic acid may r...
I applied via Walk-in and was interviewed in Jan 2023. There were 2 interview rounds.
The payscale for Plant Operators varies depending on location, experience, and industry.
Payscale can range from $15 to $35 per hour

I applied via Referral and was interviewed in Aug 2022. There was 1 interview round.
Vilsmeier-Haack reaction is a chemical reaction used to form aldehydes and ketones from aromatic compounds.
Involves the reaction of an aromatic compound with DMF and POCl3
Produces an intermediate that can be hydrolyzed to form the desired aldehyde or ketone
Can also be used to form imines and amides
Named after the chemists who discovered it: Albrecht Vilsmeier and Rudolf Haack
I perform a variety of name reactions depending on the project requirements.
I have experience with common name reactions such as Grignard reaction, Friedel-Crafts reaction, and Wittig reaction.
I also have experience with more specialized reactions such as Suzuki-Miyaura coupling and Stille coupling.
The choice of reaction depends on the specific goals of the project and the starting materials involved.

2 coding questions and 20 mcq
You are given a grid containing oranges where each cell of the grid can contain one of the three integer values:
Find the minimum time required to rot all fresh oranges in a grid.
Use Breadth First Search (BFS) to simulate the rotting process.
Track the time taken to rot all oranges and return -1 if any fresh oranges remain.
Handle edge cases like no fresh oranges or all oranges already rotten.
Consider using a queue to efficiently process adjacent oranges.
Ensure to update the grid with the new state of oranges after each second.
Given a natural number N
, return the sum of all its proper divisors.
A proper divisor of Y
is defined as a number X
such that X < Y
and Y % X = 0
.
T...
Calculate the sum of proper divisors of a given natural number.
Iterate from 1 to sqrt(N) and check for divisors
If a divisor is found, add it to the sum and also add N/divisor if it is not the same as divisor
Return the sum as the result

Technical interview
Given an array ARR
consisting of non-negative integers, rearrange the numbers to form the largest possible number. The digits within each number cannot be changed.
Rearrange the array elements to form the largest possible number by concatenating them.
Sort the array elements in a custom comparator function to get the largest number.
Convert the sorted array elements to strings and concatenate them to form the final number.
Handle cases where the numbers have the same prefix by comparing the concatenated forms.
Tip 1 : Be clear about whatever you have mentioned in resume, don't mention buzz words, because interviewer can go in depth
Tip 2 : Along with DS and Algo, if you have 3-4 months experience or internship experience, then be ready to answer scenario based technical questions like scaling the application that you developed and design concepts that can be used for improving
Tip 3 : Last but most important tip is to be calm through out the whole process ,don't loose hope if any round didn't go well ,if you have explained your thought process there is still chance to procees to next round so keep preparating for next rounds.
Tip 1 : Keep it one page resume and mention keywords which align with your technical and personal competencies.
Tip 2 : Mention 3-4 projects in the order that , project which you can explain best should be at top,then the next, and so on.
