When answering this question, interview coach Pamela Skillings recommends being accurate (share your true strengths, not those you think the interviewer wants to hear); relevant (choose your strengths that are most targeted to this particular position); and specific (for example, instead of “people skills,” choose “persuasive communication” or “relationship building”). Then, follow up with an example of how you've demonstrated these traits in a professional setting.

GSM

- GSM uses multiple frequencies.

- Uses TDMA and FDMA for accessing signals.

- The voice rate is 9.6 KBPS.

- Uses less bandwidth.

CDMA

- CDMA uses single frequency as carrier.

- The voice rate is 14.4 KBPS.

- CDMA power control to access method is better as Phased Locked Loops are used.

- Follows soft handoff, hence call handling is more efficient

It is an electronic downbridge which is used to enhance the security of a network. It’s configuration has two components.

i) Two routers

ii) Application gateway

the packets traveling through the LAN are inspected here and packets meeting certain criteria are forwarded and others are dropped.

Hint: Ideally the same things that this position has to offer. Be specific.

WDM is conceptually the same as FDM, except that the multiplexing and demultiplexing involve light signals transmitted through fiber optics channel.

It is a wireless LAN technology designed to connect devices of different functions such as telephones, notebooks, computers, cameras, printers and so on.

FDM is an analog technique that can be applied when the bandwidth of a link is greater than the combined bandwidths of the signals to be transmitted.

ICMP is Internet Control Message Protocol, a network layer protocol of the TCP/IP suite used by hosts and gateways to send notification of datagram problems back to the sender. It uses the echo test / reply to test whether a destination is reachable and responding. It also handles both control and error messages.

TDM is a digital process that can be applied when the data rate capacity of the transmission medium is greater than the data rate required by the sending and receiving devices.

It is the mode of communication between two devices in which flow of data is unidirectional. i.e. one can transmit and other can receive.

E.g. keyboard and monitor.

A generic term for section of a large networks usually separated by a bridge or router.

It is the mode of communication between two devices in which flow of data is bi-directional and it occurs simultaneously. Here signals going in either direction share the capacity of the link.

E.g. telephone

It is the mode of communication between two devices in which flow of data is bi-directional but not at the same time. ie each station can transmit and receive but not at the same time.

E.g walkie-talkies are half-duplex system.

Multiplexing is the process of dividing a link, the phycal medium, into logical channels for better efficiency. Here medium is not changed but it has several channels instead of one.

In addition to learning whether people like the products you use at your company, this question helps you evaluate enthusiasm and knowledge. Do candidates get animated when discussing the benefits of certain tools? Do they seem to have a solid grasp of the positive and negative features of different technologies?

Questions about your family status, gender (“How would you handle managing a team of all men?”), nationality (“Where were you born?”), religion, or age, are illegal—but they still get asked (and frequently). Of course, not always with ill intent—the interviewer might just be trying to make conversation—but you should definitely tie any questions about your personal life (or anything else you think might be inappropriate) back to the job at hand. For this question, think: “You know, I’m not quite there yet. But I am very interested in the career paths at your company. Can you tell me more about that?”

In asking this interview question, “your interviewer wants to get a sense of how you will respond to conflict. Anyone can seem nice and pleasant in a job interview, but what will happen if you’re hired and Gladys in Compliance starts getting in your face?” says Skillings. Again, you'll want to use the S-T-A-R method, being sure to focus on how you handled the situation professionally and productively, and ideally closing with a happy ending, like how you came to a resolution or compromise.

The duration of time it takes to send a message from one end of a network to the other and back, is called RTT.

OK, if you get the admittedly much tougher follow-up question as to why you were let go (and the truth isn't exactly pretty), your best bet is to be honest (the job-seeking world is small, after all). But it doesn't have to be a deal-breaker. Share how you’ve grown and how you approach your job and life now as a result. If you can position the learning experience as an advantage for this next job, even better.

Don't be thrown off by this question—just take a deep breath and explain to the hiring manager why you've made the career decisions you have. More importantly, give a few examples of how your past experience is transferrable to the new role. This doesn't have to be a direct connection; in fact, it's often more impressive when a candidate can make seemingly irrelevant experience seem very relevant to the role.
