11 Questions

  • Q1. About your work experience
  • Q2. Sequence detector
  • Q3. I2c protocol thoroughly
  • Q4. Spi protocol
  • Q5. Difference between spi & i2c,difference between latch & ff
  • Ans. 

    SPI and I2C are communication protocols used for connecting devices, while latch and FF are different types of sequential logic elements.

    • SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) are both serial communication protocols used for connecting devices in embedded systems.

    • SPI uses separate lines for data input and output, while I2C uses a shared bus for both input and output.

    • SPI supports higher dat...

  • Q7. 2 identical pills
  • Q8. Find the average speed for a particular ditance is the average speed while going is x.find out the speed of whole trip...(something like that)
  • Ans. 

    To find the average speed for the whole trip, we need to know the distance and the time taken for the trip.

    • Average speed = Total distance / Total time

    • If the distance and time for the trip are known, the average speed can be calculated.

    • If only the average speed while going is known, we cannot determine the speed of the whole trip without additional information.

  • Q9. A circular wheel and a sensor.find out the direction of rotation(related to digital)
  • Q10. Cricket match.maximum run achieved by batsman(he dropped the idea of asking as i have 0 knowledge of game)
  • Q11. Probability of getting heads maximum two times
  • Ans. 

    The probability of getting heads maximum two times in a series of coin flips.

    • To calculate the probability, divide the number of favorable outcomes by the total number of possible outcomes.

    • In this case, the favorable outcomes are 0, 1, or 2 heads, and the total possible outcomes are 2^n, where n is the number of coin flips.

    • For example, if we flip a coin 3 times, the favorable outcomes are HHT, HTH, THH, HHH, TTH, THT, a...

Interview preparation tips for other job seekers - When you know the answer, be very concise with your answer, try to explain without rambling with minimum word count.
When you don't know the answer try repeating the question back to interviewer to be super clear about the question and then say that currently you don't hold that much clarity about the topic but you will learn it soon.
