Hello All, I am new in this forum, I want to know how to crack my upcoming Linux interview. I am fresher and I have good knowledge about basic components of Linux, BASH and DOS, symbolic links, daemons. Can anyone suggest me some tricks to crack my upcoming interview?

Hi,

welcome to the forum. Perhaps you could tell us exactly what you mean by "Linux Interview"? Are you talking about an interview for some sort of employment?

I want to look the list of most important Linux interview questions as a fresher level.

Hi,

Ok, I still don't know what you are talking about. Perhaps someone else knows what you want.

That's what duckduckgo produced...

Some of those questions and the hilariously wrong answers are great!

Questions will depend on job position and requirements.

Not exactly sure what you mean by "tricks to crack an interview"??

+1 this was my thought.

Less about the technology vs. instead what the position is really about.

Read the job description, see if you fulfill the minimum requirements, or if you come close. Ask to know more about the position if you get a chance. This really is a two way street. Most common sense employers are not interested in getting a body hired, but instead getting someone who will fit within their organization, as well as someone who has the skills, attitude, and resourcefulness to be able to take on work in their organization. It should be more than just "knowing an answer".

Hi,

Welcome to LQ!

First, you state that you have an up coming interview. What position is that interview for? Entry level? You have work experience in IT or working with requirements listed for the to be interview position?

There is no magic bullet for interviewing. You need to have experience along with knowledge within the field of choice. Your verbal skills will be important in order to convey information and response to the interviewer as a potential candidate for the position.

One real important point is how you present yourself. I have seen potential interviewees over dress for entry level positions. Your demeanor along with your personal hygiene (i.e. do not over use your cologne). Clean cut and proper attire will get you points whenever you interview with me. Male or female doesn't matter but how one does present themselves for the position does.

If you come across as overly nervous then you may not seem prepared for the potential job. Confidence in one's abilities is good but do not go into the interview over confident. Steady and clear speech will come across as a communication skill. If your verbiage is wording then you may not get a toe into the door. Your manner or style of expressing will be noted when speaking with someone in an interview. Conveyance is very important when speaking about your field of experiences and knowledge.

Hope this helps.
Have fun & enjoy your interview!

As a junior your skills and knowledge about your chosen field won't be as important as your attitude, curiosity, drive, enthusiasm.

If you can demonstrate that you are a self motivated, enthusiastic, reasonably intelligent individual who's curious and has an ability to problem solve and willing to learn, that will get you further than being able to answer common interview questions. As has been said, also ask about the job and company. Show an interest in them.

To get answer of these question just visit here: [Removed spam]

No - It is a patchwork quilt stitched together from the efforts of a multitude.
The former is an albatross, while the latter is a dodo.
htop
Requires far less words than Windows.
What platforms need to be supported?
Like Windows shortcuts, only visible.
Fairies that magically do what is needed when required.
Who uses that anymore?
Nothing in a properly designed modern operating system.
Sequential pipeline or multiple background jobs?
Something that needs eradicating.
Please explain why case sensitivity is not an issue in Windows.
There is no such thing.
Whiteboards are so passe.
I thought this was an interview about Linux.
Let me count the ways.
It depends.

There you go. A perfect 0/17.

No, you are showing *SOME* of the commands, with little to no explanation of what they do.
And these questions are pointless. You are aware that an interviewer can ask ANYTHING THEY WANT right? And that they can accept any answer they want? The only way to prepare for ANY interview, for ANY position, is to know what you're doing. There isn't a 'guide' on what questions they are allowed to ask, nor are there any shortcuts...
..like the one posted.

no comparison
dos was an OS, bash is a shell

complicated
but
is a start
has none that I'm aware of
you can have different tabs on your desktop with different programs showing
I don't think many people use it on purpose.
programs that do things when you are not looking
does anyone use vi?
don't know
find /usr/local
at the same time?
I never mentioned hard links
and I don't think the Linux Kernel has them.
IT HAS NONE
made by an idiot or someone up to no good
in his diving gear maybe,
It looked better in my head
give us an etcha-sketch I'll try again.

what?
Ohh, yeah I always get those mixed up.

why would a web server need curl?

sudo -i

If I did that it probably wouldn't compile
vim can do each of those
