I applied via Approached by Company and was interviewed before Jan 2024. There were 3 interview rounds.
50 marks objective fully electrical domain
Relays are used for various functions such as protection, control, and monitoring in electrical systems.
Types of relays include protective relays, control relays, and monitoring relays
CT (Current Transformer) and PT (Potential Transformer) are used for measuring current and voltage in electrical systems
Types of breakers include circuit breakers, fuse breakers, and earth leakage circuit breakers
Identifying symbols from electrical schematics is crucial for an Electrical Design Engineer.
Study the legend/key provided with the schematic to understand the symbols used
Look for common symbols such as resistors, capacitors, diodes, transistors, and connectors
Pay attention to the shape, size, and orientation of the symbols to differentiate between components
Use reference materials or software tools to cross-check and
I applied via Approached by Company and was interviewed in Nov 2023. There were 3 interview rounds.
Ckt theory machine ps measurment
Relays are used to control circuits by opening or closing contacts based on electrical signals, while circuit breakers are designed to protect circuits from overloads and short circuits by interrupting the flow of current.
Relays are used for switching purposes, while circuit breakers are used for protection purposes.
Relays operate based on electrical signals, while circuit breakers respond to current flow.
Relays have c...
Microgrid is a localized group of electricity sources and loads that normally operates connected to and synchronous with the traditional centralized grid.
Microgrid is a small-scale power grid that can operate independently or in conjunction with the main power grid.
It can include distributed energy resources like solar panels, wind turbines, and batteries.
Microgrids are often used to increase energy reliability, reduce...

Round difficulty - Medium
Asked about time complexity of algorithm, puzzles, DBMS, cutting edge technologies etc. What are indexes?
Given an array of integers ARR
of size N, consisting of 0s and 1s, you need to select a sub-array and flip its bits. Your task is to return the maximum count of 1s that can b...
Given an array of 0s and 1s, find the maximum count of 1s by flipping a sub-array at most once.
Iterate through the array and keep track of the maximum count of 1s obtained by flipping a sub-array.
Consider flipping a sub-array from index i to j and calculate the count of 1s in the resulting array.
Return the maximum count of 1s obtained by flipping a sub-array at most once.

You are provided with a 2-dimensional matrix having N
rows and M
columns, containing only 1s (land) and 0s (water). Your goal is to determine the number of islands in t...
Count the number of islands in a 2D matrix of 1s and 0s.
Iterate through the matrix and perform depth-first search (DFS) to find connected 1s.
Mark visited cells to avoid redundant traversal.
Increment island count whenever a new island is encountered.
Tip 1 : prepare for competitive programming
Tip 2 : know about standard algorithm
Tip 3 : must be good with dbms
Tip 1 : must have projects, which you can explain to them
Tip 2 : have things on resume, that you are totally certain about.

Joins are used to combine data from two or more tables based on a related column.
Types of joins include inner join, left join, right join, and full outer join.
Inner join returns only the matching rows from both tables.
Left join returns all rows from the left table and matching rows from the right table.
Right join returns all rows from the right table and matching rows from the left table.
Full outer join returns all row...

Hashmap is a data structure that stores key-value pairs and allows for fast retrieval of values based on keys.
Hashmap uses a hashing function to map keys to indices in an array.
It allows for constant time complexity O(1) for insertion, deletion, and retrieval operations.
Example: HashMap<String, Integer> map = new HashMap<>(); map.put("key", 123); int value = map.get("key");
