Cable Operator Interview Questions And Answers

This question seems simple, so many people fail to prepare for it, but it's crucial. Here's the deal: Don't give your complete employment (or personal) history. Instead give a pitch—one that’s concise and compelling and that shows exactly why you’re the right fit for the job. Start off with the 2-3 specific accomplishments or experiences that you most want the interviewer to know about, then wrap up talking about how that prior experience has positioned you for this specific role.

Again, companies want to hire people who are passionate about the job, so you should have a great answer about why you want the position. (And if you don't? You probably should apply elsewhere.) First, identify a couple of key factors that make the role a great fit for you (e.g., “I love customer support because I love the constant human interaction and the satisfaction that comes from helping someone solve a problem"), then share why you love the company (e.g., “I’ve always been passionate about education, and I think you guys are doing great things, so I want to be a part of it”).

A receiver receives a signal before it becomes too weak or corrupted,regenerates the original bit pattern,and puts the refreshed copy back onto the link.It operates on phycal layer of OSI model.

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.

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.

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 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?

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

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.

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

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 unidirectional. i.e. one can transmit and other can receive.
E.g. keyboard and monitor.

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

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.

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.

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

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.

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.

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

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.

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

First of all, be honest (remember, if you get this job, the hiring manager will be calling your former bosses and co-workers!). Then, try to pull out strengths and traits you haven't discussed in other aspects of the interview, such as your strong work ethic or your willingness to pitch in on other projects when needed.

A network is a set of devices connected by physical media links. A network is recursively is a connection of two or more nodes by a physical link or two or more networks connected by one or more nodes.
