Q1. I was asked to write two sum, palindrome function and merge sort code in whatever language I'm comfortable in
Add your answer
Q2. Two sum- return true or false
Ans. 
Given an array of integers, determine if there are two numbers that add up to a specific target.
• Iterate through the array and store each element in a hash set.

• For each element, check if the difference between the target and the element exists in the hash set.

• If the difference exists, return true; otherwise, continue iterating.

• Example: nums = [2, 7, 11, 15], target = 9. The function should return true as 2 + 7 = 9.

Q1. Find equivalent capacitance for a infinity ladder structure.
Ans. 
Equivalent capacitance for an infinity ladder structure can be found using the concept of series and parallel capacitance.
• An infinity ladder structure consists of an infinite number of identical capacitors connected in a ladder-like pattern.

• The capacitance of each individual capacitor in the ladder is assumed to be C.

• To find the equivalent capacitance, we can consider the structure as a combination of series and parall...read more

Q2. Find circuit v ,i and equivalent resistance
Ans. 
To find circuit v, i, and equivalent resistance
• Analyze the circuit to determine the voltage (v) and current (i) at specific points

• Use Ohm's Law (V = IR) to calculate the voltage or current if resistance is known

• To find equivalent resistance, combine resistors in series or parallel using appropriate formulas

• Apply Kirchhoff's laws to solve complex circuits

Q1. Find the current during SC and open circuit conditions
Ans. 
The current during SC (short circuit) and open circuit conditions depends on the specific circuit and components involved.
• During short circuit conditions, the current will be very high as there is a direct connection between the power source and ground.

• During open circuit conditions, there will be no current flow as the circuit is not complete.

• The specific values of current during SC and open circuit conditions can onl...read more

Q1. Design a circuit which predicts majority ones
Ans. 
Design a circuit to predict majority ones in a given input
• Use a majority gate to determine if the input has more ones than zeros

• Implement a comparator to compare the number of ones and zeros in the input

• Utilize flip-flops to store and compare the bits in the input

Q2. Different types of memory units
Ans. 
Different types of memory units include RAM, ROM, cache memory, virtual memory, and flash memory.
• RAM (Random Access Memory) - volatile memory used for temporary storage

• ROM (Read-Only Memory) - non-volatile memory used for permanent storage

• Cache Memory - high-speed memory used to store frequently accessed data

• Virtual Memory - uses disk space as an extension of RAM

• Flash Memory - non-volatile memory used in USB drives, SS

Online Test

There were 3 colleges writing the online test(pool campus).Cut off was about 70% with no backs .This was probably the hardest of the entire recruitment process. It had about 20 technical and 20 aptitude questions and questions had NEGATIVE MARKING.

Technical questions were majorly focused on Circuit theory, network theorems, dependent source problems, time constant calculations, RC circuits and its graphs, and a very few problems on communication theory and signals and systems/DSP. The questions are actually easy provided you have solved those topics before hand . Do understand the behavior of RC circuits by watching a few videos on YouTube. Understand dependent source problems and solve problems based on those topics. If you study the subject Electric Circuit Analysis(ECA), which was part of our syllabus it would be sufficient. Again, don't study everything in ECA, focus on the topics mentioned above.

Aptitude questions were quite straight forward with mathematics involved, and some English/vocabulary based questions. Attend the placement training properly, you can grasp most of the concepts and attend many of the online tests with ease.
