There are two stages:
1. Written test ---> contains three parts Reasoning, Quant and Verbal. There are questions on,
- Data interpretation (5),
- Data sufficiency (5),
- Circular arrangement (5),
- Time and work (1),
- Numbers (1),
- Cryptarithmetic (1),
- Geometry (simple sum),
- Long passage,
- Short passage,
- Sentence correction and some questions testing grammar.
The time management is the major important thing in written test.
Out of 1302 students, 422 were qualified for next round.
2. Technical and HR:
1) Tell me about yourself?
Answer confidently.
2) Explain me about your projects?
I explained about my projects for about 10 minutes.
3) What is modulation?
Addition of information to an electronic carrier signal.
4) Difference between analog and digital signal?
Explained it.
5) What is duplexer? Which acts as both transmitting and receiving antenna example mobile phone.
6) What is full duplex and half duplex?
full duplex->transmission in both direction simultaneously.
Half duplex->transmission in either direction simultaneously.
7) Draw an ex-nor gate and truth table?
I got confused and wrote truth table for (Ex-OR) Gate when the TR told that I wrote wrong I said no I wrote right but saw my mistake and told him I was confused.
It\'s okay to do a mistake and get confused but don\'t let it effect you in answering the next questions.
8) Explain amplitude and frequency modulation and where do we use them?
Change in the amplitude of the carrier signal in accordance with information bearing signal. (video signals) change in the frequency of the carrier signal in accordance with information bearing signal (audio signals).
9) What is multiplexing?
Multiple analog message signals and digital data streams are combined into one signal over a shared medium.
10) What is amplifier?
Electronic device or electronic circuit which is used to boost the power, voltage and current of an applied signal.
11) What is CDMA?
All users share the same frequency all the time. Every bit of conversation is been tagged with a specific and unique code and I explained a real life example of luggage at airport.
12) What is an oscillator?
Circuit which creates a waveform output from a direct current.
13) What is the difference between CDMA and GSM?
I said I don\'t know.
14) What type of medium is better for transmission?
At that time air medium is the only thing that struck me so I said air medium. TR asked me, I think optical is better option. I explained him the disadvantages in optical and advantages in air medium and even though there are disadvantages in air medium transmission how we can overcome them in future.
15) Do you have any questions?
Prepare some questions before hand.
Most of my questions, as you can see, are from basics be thorough in your basics. Know about the present technologies such as big data, cloud computing, Internet of Things like that.
236 were placed and I am happy to be one of them.
All the best never loose hope.
