Some basic probability/stochastic process questions about lossy wireless channels.
The last question the interview asked was: "Suppose we make 10 packet transmissions per second over a wireless channel, the channel is lossy such that with probability 1/10 a packet transmission will fail. The transmitter knows perfectly whether a transmission succeeds or fails. When it fails, the transmitter retransmit the packet, until it finally succeeds. So what is the throughput we can get?"
This was a VERY VERY simple question that the throughput should be 9 packets/second! The interview didn't agree and simply emphasized "because of retransmission, throughput should be reduced more than 1/10" repeatedly.
Couldn't achieve a consensus with him after a long debate and that's it.

Domanda 1
Given a wireless channel with loss rate 0.1, what's the throughput one can get with retransmission.

Colloquio
I got an email about a phone (screening) interview about two weeks after application. Then, one week later, I was invited for an on-site interview along with 1-hour presentation about my recent research. After one week, I had a virtual (on-site) interview consisting of five individual one-on-one interviews (four technical + 1 HR) right after my research presentation.

Domanda 1
- First-round question: I was asked about what I have done in detail from my resume.
- Second-round question: 1-hour research presentation and several technical questions on LTE RAN protocols and some basic questions on OFDM and difference between EPC and 5GC, and a few behavioral questions (only during the interview with one HR interviewer)

Colloquio
Overall, it was a great experience. First round was a phone screen. After clearing that, you are required to provide a 1-hour presentation on your PhD work. This is followed by back-to-back interviews.

Domanda 1
The questions were primarily related to probability and statistics, queuing theory, optimization, and wireless communications and networking. A strong foundation in mathematics is needed.
It was a one hour phone interview that included first introducing yourself, then your previous work experience and for the last 20 minutes included few questions on basic signal processing and wireless communications.
