Interview
There were around 8 - 10 panels for tech intrw held at TCS, Karapakkam, Chennai. Environment was excellent.
People from TCS were very soft and had a cheerful face.
In my panel, two persons of age around 35 – 40 yrs interviewed me. Tech intrw was held for around 55 min. Slightly drilling but easy. After clearing tech, I attended HR where one young man interviewed me.It went for half an hour exactly. Most of them were only personal questns and some tech Qs. On my time slot, 5 ppl attended in that same panel and only 2 cud get thro.
For another friend, the tech held for just 10min.They asked 2 gen. Qs like where he is from (Ambattur) and how he reached that office.Then 2 tech Qs 1) Shannons theory ? Ans: “I don’t know”2) Diff betn up85 & 86. He told correctly.He got selected.
So, it depends on ur luck to get a good panel.

Technical Interview
1. Introduce ur self.
1. Introduce ur self.
2. First person started…..He asked my mark sheets from which Qs were poured from various subj I’d studied in my BE (ECE) syllabus………
3. Favourite subj.? Digital
4. How abt mp?Draw the architecture of 8085?Explain each block? Interrupts and its types? Flags?
5. Write a program to multiply 2 nos? Diff betn MOV & MVI? Diff betn 85 & 86And some more………?Latest mp used?
6. Next person started…..Whats inside a CPU of PC? Inside processor? Whats a MODEM? working? If 2 PCs connected to a server using 2 MODEMs, what is the fn of each modem?
7. Back from first person…meanwhile the 2nd person was going through my marksheets and certificates. Lets move 2 ur fav subj…Digital -Draw the diag of OR and NOR? OR internal ckt diag ? I managed to draw a diag which is logically correct ( with 2 transistors …..) Universal gates? Why? Draw OR using NOR gates? What is multiplexed?
8. Slowly deviated to analog-Describe abt transistor? Types? Types of BJT? Diag for NPN and PNP? Differentiate where they r used? Uses of transistor according to mode of opn.? Uses of diode? How it is used as rectifier? Zener diode? What is bias? What is thyristor? SCR? Where used? Diff betn thyristor & transistor? And some more………………
9. Then programming…… How good u r with programming? I know only C. Asked me to write a pgm. I’m not well versed with programming. I knowonly conceptually. Why pointers? Answered Luckly, they skipped the topic.
10. Then……Network Topologies? Bus, ring… What u know in networking? I know only the basics as this was not choosen as our elective. Then whats ur elective? Biomedical……..(I think the person was good in that subj.)
11. I was caught …………He fired several questions like… How ECG working? Stethoscope working? BP ? and more………………… How pressure converted to signal? Transducers?
12. Then came to the project…Explain ur proj. I explained clearly with proj report. Some Qs on project. I myself added that I did with 3 other studentsfrom different states and could manage to complete the project successfully.
13. Finally general Qs…You did a proj in digital design and why do u want to come to software? Why not hardware? What guarantee u give that u won’tshift to hardware after 2 yrs saying u don’t like S/w? Another person asked what u studied in Engineering economics & mgmt? R u interested in this subj? I frankly said it’s a bit boring subj. ‘coz there is nothing to learn and this is the subj where we write stories. They smiled. If we put u in proj dealing with mgmt,…..difft from what u’ve studied in BE, r u ready to do that?
U said it’s a boring subj. & now ready to switch over to that ? First of all, working at TCS itself is a great pleasure and it would be my duty to develop interest in that subject and shine well in that area. Finally they asked ‘any Qs 2 us’? Yes sir! On what electronics related proj r u working currently? Then I smiled and said ‘then there is a chance for me to get into electronics based s/w projects’.
