Interview Experience shared by
Vaishali Bansal, Income Tax Inspector
CGL 2013 AIR-3
Marks Scored: 72/100
Stage 1 (Pre Interview)
Bio data form: I filled my bio-data completely trying not to leave out any blanks as well as not writing things that are not true. Bio-data is your mini biography depicting what you are now and what you have been doing till now covering every aspect of your life. Try presenting yourself in a good and a positive way. Every column has some marks in it. Also, do prepare questions which can be asked based on every keyword you mention in your bio-data form.
Topics Prepared: Focused on my graduation, that is basic technical subjects like Communication, Analog and Digital electronics, Antennas, Microwave, Computer networking, Electromagnetism. Thereafter, the newspapers to cover the policies etc. Also the typical HR questions (google it), basic GS, Indian Polity, Economics, Science, Hobbies and extra-curricular.
Stage 2 (Interview Day)
What Attire to wear (esp. for girls): Your attire gives the first impression about you which can decide the overall classification of you from being nerdy to messy to smart and well dressed. Clean and neatly tied hairs that’s important for girls. You have to look professional and not someone who is out on a ramp walk or going to a marriage function. I chose neutral colors: blue shirt, bluish grey trousers, black blazer and formal bellies.
Last minute preparation: Just revised whatever material I already had with me.
Topper’s Tip: Interviewers generally don’t repeat their questions so asking and enquiring others what was asked of them is a complete waste of time.
Interview board 6: The panel had 3 people: 2 ladies and 1 gentleman
Interviewee background: B.Tech in ECE
Mentioned hobbies: reading novels, yoga, ECA: paper presentation
Q 1. What is difference between GSM and CDMA? (Graduation related question)
A 1. (Answered satisfactorily)
CDMA: code division multiple access. There is one physical channel and a special code for every device in the coverage network. Using this code, the signal of the device is multiplexed, and the same physical channel is used to send the signal.
GSM: global system for mobile comm. Every cell has a corresponding network tower, which serves the mobile phones in that cellular area.
Q 2. Which is more secure: CDMA or GSM? (Graduation related question)
A 2. (Answered): CDMA
Q 3. Why CDMA? (Graduation related question)
A 3. (Answered): Because of the special code, if the unwanted person doesn’t have that code the signal is just noise for them
Q 4. Percentage of total world population using CDMA? (Graduation related question)
A 4. (Didn’t knew the answer): Said sorry, I don’t know the answer
Q 5. Asked about LTE and features/functioning of LTE. (Graduation related question)
A 5. (Answered): LTE is Long-Term Evolution, increased data transmission speeds and lower latency, further development of cellular technology i.e. faster data rates for both uploading and downloading. Features like conference calling, video conferencing, better voice and video quality etc.
Q 6. Asked about 1G, 2G, 3G and 4G; differences and how technology improved with example. (Graduation related question)
A 6. (Answered: easy question, any ECE engineer should be knowing)

Q 8. Difference between Bluetooth and Wi-Fi. (Graduation related question)
A 8. (Answered, any technical graduate must be knowing this)
Bluetooth technology is useful when transferring information between two or more devices that are near each other when speed is not an issue, such as telephones, printers, modems and headsets. It is best suited to low-bandwidth applications like transferring sound data with telephones (i.e. with a Bluetooth headset) or byte data with hand-held computers (transferring files) or keyboard and mice.
Wi-Fi is better suited for operating full-scale networks because it enables a faster connection, better range from the base station, and better wireless security (if configured properly) than Bluetooth.
