Hariharan Foundations Interview Questions and Answers for Experienced
6 Interview questions
The phase to neutral voltage depends on the type of electrical system being used.
In a single-phase system, the phase to neutral voltage is equal to the line voltage.
In a three-phase system, the phase to neutral voltage is equal to the line voltage divided by the square root of 3.
For example, in a 120V single-phase system, the phase to neutral voltage is 120V.
In a 208V three-phase system, the phase to neutral volta...
Neutral to Earth voltage is the potential difference between the neutral wire and the earth.
Neutral to Earth voltage is typically very low, ideally close to zero.
It is important to maintain a low Neutral to Earth voltage to ensure electrical safety.
Neutral to Earth voltage can be measured using a voltmeter.
If the Neutral to Earth voltage is high, it may indicate a fault in the electrical system.
Neutral to Earth vo...
Phase to phase voltage is the voltage between two phases in a three-phase electrical system.
Phase to phase voltage is used in three-phase electrical systems.
It is the voltage between two phases, such as phase A to phase B or phase B to phase C.
The phase to phase voltage is typically higher than the phase to neutral voltage.
In a balanced three-phase system, the phase to phase voltage is equal to the square root of ...
Induction motors work on the principle of electromagnetic induction to convert electrical energy into mechanical energy.
Induction motors have a stator and a rotor.
When an alternating current is supplied to the stator windings, a rotating magnetic field is created.
This rotating magnetic field induces currents in the rotor windings, which in turn creates a magnetic field.
The interaction between the stator and rotor ...
RCCB stands for Residual Current Circuit Breaker. It is an electrical safety device used to protect against electric shock.
RCCB is installed in the electrical distribution board.
It detects and quickly interrupts the circuit if there is a leakage current.
To work on RCCB, follow these steps:
1. Ensure the power supply is switched off.
2. Open the electrical panel and locate the RCCB.
3. Check for any visible damage or ...
Ohm's Law states that the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to its resistance.
Ohm's Law relates the three fundamental electrical quantities: current, voltage, and resistance.
The equation for Ohm's Law is I = V/R, where I is the current, V is the voltage, and R is the resistance.
This law helps in understanding and calculating the behavio...

Interview Preparation Tips
Experience: Students were shortlisted based on resume. Around twenty students were selected.
Round: Other Interview
Experience: Selected students for the first round of interview in which they asked puzzles/probability questions and tough HR questions.
Round: HR Interview
Experience: Four students were selected for the final round of interview out of which three landed the job. Final round was a very general HR round.
General Tips: No preparation is required but you could solve some common puzzles. It was very relaxed and the interviewers were very supportive. The main challenge was giving convincing answers to the HR questions.It's the best management job on campus!! Give your best! I'll be glad to help if any of you have queries.
Skill Tips: Make a very professional resume. Also for the interview, they do not expect you to know any finance so please do not claim to know finance and fumble when they question you (some guys were not selected because of this). I was upfront and told them that I lack any sort of knowledge in finance so I was asked only a few puzzles and some challenging HR questions.

- Q1. Probability and Logical puzzles
Interview Preparation Tips
Experience: The company shortlisted based on resume and GPA. Around 20 were shortlisted.
Round: Technical Interview
Experience: After that they held a technical round wherein they asked mainly probability and logical puzzles. Theinterview was 10 to 15 mins long.
Round: HR Interview
Experience: The next round, for which five or so were shortlisted, was one in which they asked about your drive, your good and your bad, why finance, why this job, and other such questions. All the interviewers were present and this lasted for 15 minutes. Finally only 3 were given the offer.
General Tips: Look formal and energetic. Look them in the eye while answering, be courteous and practice thinking loudly. Think about what you would say when they ask you why you want to move to finance, and whythey should take you and not the others. It is not a tough one to crack. All you need is to be confident, polite and frank.
Skill Tips: Prepare your resume tailored to the company. Study up probability and tricky questions on it. They asked me a question on Russian roulette. Prepare for puzzles online.
