My Interview with Intel

I had an interview last week with Intel. This post will be used as my reminder in future!

Honestly, the questions asked were fundamental but I am unprepared for their technical questions. Did not do my revision! This was my greatest downfall.

Besides the normal questions such as "introduce yourself, your interest, your capability, ect ect", these are the summary of the questions asked and answers:

1. Draw a CMOS inverter truth table, schematic, stick diagram and cross-sectional view.
2. Draw a CMOS NAND and NOR gate truth table, schematic, and stick diagram.
Answer:

CMOS NOT, NAND, and NOR

3. Design an XOR gate using only NAND gate.
Answer:

Design XOR using NAND gate

4. Design XOR gate using only NOR gate.
Answer:

Design XOR using NOR gate

5. Write a simple source code to sort 10 numbers in descending order.
Answer:

6. Design half adder and full adder, from truth table, simplify using Karnaugh Map and draw the schematic. (lazy to write the solution)

7. What are the 5 layers in physical layer. (I only learn the 7 OSI layers. Not the layers inside the physical layers)
Answer: The 7 layers are Application, Presentation, Session, Transport, Network, Data Link and Physical.

8. What are the functions of data link layer?
Answer: Provide node to node packet delivery service, transmission/reception of structured streams of bits over the network media, sub-divide the physical layer's raw bit stream into structured blocks of packets, error detection and error handling.
