- Q1. What is the difference between a while loop and a do while loop?
- Ans.
A while loop checks the condition before executing the code block, while a do while loop executes the code block once before checking the condition.
While loop: Condition is checked before entering the loop.
Do while loop: Code block is executed at least once before checking the condition.
Example: while (condition) { // code block } vs. do { // code block } while (condition);
- Q2. How the boost converter will work?
- Ans.
Boost converter is a type of DC-DC converter that steps up the input voltage to a higher output voltage.
Boost converter uses an inductor, a diode, a capacitor, and a switch to increase the voltage level.
During the switch on-time, energy is stored in the inductor. During the switch off-time, the energy is transferred to the output.
The output voltage is higher than the input voltage due to the energy transfer process.

Do-while loop: Similar to while loop but guarantees at least one execution. Example: do {} while(condition);
- Q2. Explain Timers and counters
- Ans.
Timers and counters are essential components in embedded systems used for measuring time intervals and counting events.
Timers are used to measure time intervals by counting clock cycles or external events.
Counters are used to count external events or pulses.

Interview Preparation Tips
I applied via referral in Deloitte USI but to save their referral bonus (I guess), they rejected my profile on the portal and called me through Naukri.com. When I asked them the reason, they said its for a different profile them. however it was for the same one.
Also on their career site, it was not mentioned that role is of fixed term hire (for 2 years), but HR disclosed it later, during the conversation. (another discrepancy)
During my initial conversation, HR clearly said there won't be any night shifts and I would have to work from client's location in Gurgaon office. Although it is 2 year contractual role.
But during my technical interview, the person clearly said to me that I would have to relocate to Bangalore for working from client's secured ODC in office. Also there would be rotational/ night shifts (without any extra pay). Basically they were looking for someone who would devote his 24X7 time to the company for a minimal salary and does not demand for work life balance or weekends off
Neither the HR nor the interviewer opened their web camera during the video call. But HR kept asking me to keep my camera open, even during the waiting time
