The 8 DON'Ts of a Job Interview

Hello My Lovely Readers,

Today I want to share some very useful tips which will definitely help you in your job hunt.

I happened to have an interview at a very flourishing company which is very good at developing the most in a very short time; the day before yesterday. And believe me after all the preparations I did, all was in vein the moment I sat in front of the interviewer.

When I came back home, I was feeling sad for my stupid behavior during the interview because I had already passed the test and now the interview was the last assessment for my job.

Then I started thinking deeply on the matter of interview and finally after almost a day, I have found some helpful DON'Ts which can easily and successfully slip you through the tough interview round.

I would like to share them with you for your future reference.

1. Arriving late for the interview.

There is no excuse for the interview tardiness. You should strictly plan in advance for the traffic jams and other logistical obstacles and should leave for the interview way ahead of your actual appointment time and reach the office at least 15-20 minutes early. Then use the bonus time to review your preparation materials.

2. Dressing unprofessionally.

You should dress according to the culture of country in which you are. Also keep in mind that body piercings and tattoos can be distracting to some interviewers, so you should limit them as much as possible.

Plus take good care of your personal hygiene. No one likes a ill-looking employee in their team.

3. Behaving disrespectfully.

Whether it be a person at the door or at the reception, the human resources professional or any other employee passing you in the hallway, you should always mind your manners through each interaction because everyone with whom you come in contact is definitely a potential influencer to the decision-maker.

It is to note that this point doesn't apply to the interview day only, but it does apply to any other day; you should always meet and greet people happily with a smile on your face.

4. The most common mistake you can make during an interview.

Not organizing yourself beforehand.

No matter how hard you try or how many hours you allocate for a good thorough internet search, you are still vulnerable to make big mistakes like I did after many hours of deep thorough study of the company profile.

Here is a picture of the notes I took during my interview preparation :)

What you have to prepare is how you will answer the questions i.e. organize information in a way that you can speak clearly and concisely plus learn to handle the situation when things go awry. Your interviewer will definitely be impressed that you went the extra mile.

5. Talking Too Much.

There is nothing much worse than talking on and on and on ... The interviewer really doesn't need to know your WHOLE life story. You should keep your answers succinct, to-the-point and focused and please don't ramble, just answer the question directly.

Plus instead of asserting your personal style, focus on what's important in the situation i.e. a dialogue that can convinces a hiring person that you will contribute selflessly to the company.

6. Not being a good listener to your interviewer.

Remember, everyone loves a person who is a good listener.

If you don’t really listen to the questions your interviewer is asking, you won’t be able to respond to them properly. You should make sure that you put on your ‘listening’ cap as well as your ‘speaking’ cap. If you don’t listen up to your interviewer, you are pretty much sunk !

7. Do you have any queries ?

Don't come up empty when this question is asked. And don't give a "deer in the headlights" look, shrug your shoulders and ask anything from your thoughts at that moment. Because if you don't ask any questions, it may appear as if you're not interested in this job which in actual is not true.

8. Forget to say thank you.

At the end say a big "thank you" in a warm manner which can demonstrate appreciation for the interviewer's time because it was their greatness that they actually called you for an interview and remember manners matter a lot, always.

Happy Job Hunting ! :)

Interrupts in 6809 microprocessor

Interrupts:
The 6809, like most other microprocessors, has instructions and the hardware to handle interrupts. Interrupts are a mechanism for allowing outside events temporarily to divert the micro from its current program. When an interrupt arrives, a call is made to a nominated routine which runs an 'interrupt service routine' ending with a 'return' instruction which returns the micro to the interrupted program. So, an interrupt is just like a subroutine call except that control is not passed explicitly to the routine by the main program, but happens independently of it.
Interrupts are used for infrequent or irregular events which must be acted upon by the processor. The use of interrupts saves having to look periodically to see whether the event has occurred or not. This is known as polling and can tie the micro up for a large proportion of the time, especially if the event is a rare one, like power failure.

Implementation of Interrupts:
Most micros have one or more pins on them devoted to interrupts. A level (usually "0") on one of these pins causes the processor to enter an interrupt service routine (ISR), whose entry address is kept in a special area in memory. This is done by means of something very like a subroutine call; the return address is pushed onto the stack. The routine completes and a return from interrupt instruction is executed, which resumes execution of the interrupted program when a return from interrupt instruction (RTI) is executed. In order to avoid chaos, further interrupts on the same pin are not usually allowed between the arrival of the interrupt and the return from the interrupt routine.
Some processors allow multiple interrupts, which means that one interrupt service routine may itself be interrupted by another ISR. This is known as nesting interrupts. Whether or not an interrupt is serviced at all may be decided by the user, who may disable and enable interrupts, so that they may be ignored if they are not relevant.

Warnings:
Interrupts can be dangerous!! Care must be taken to ensure that interrupts do not corrupt information which is being used by the interrupted routine.
Finally, the cause of an interrupt MUST be cleared (if necessary) by the micro before the RTI instruction is executed, or else the processor will be immediately interrupted again, and you get into a deadlock situation.

Static Method

Static Method:

A method may be declared as static, meaning that it acts at the class level rather than at the instance level.

Multimeter

Multimeter

A multimeter or a multitester, also known as a volt/ohm meter or VOM, is an electronic measuring instrument that combines several measurement functions in one unit. A typical multimeter may include features such as the ability to measure voltage, current and resistance. There are two categories of multimeters, analog multimeters and digital multimeters (often abbreviated DMM or DVOM.)

Quantities Measured

Contemporary multimeters can measure many quantities. The common ones are:

Voltage in volta.

Current in amperes.

Resistance in ohms.

Digital multimeters may also include circuits for:

Continuity that beeps when a circuit conducts.

Diodes and transistors

Accuracy

Digital multimeters generally take measurements with accuracy superior to their analog counterparts. A multimeter's quoted accuracy is specified as being that of the lower (mV) DC range, and is known as the "basic DC volts accuracy" figure. Higher DC voltage ranges, current, resistance, AC and other ranges will usually have a lower accuracy than the basic DC volts figure.

Burden voltage

On both DC and AC current ranges a multimeter will cause voltage drop in the circuit under test. This is primarily due to the current shunt resistor used for measurement. This voltage drop is known as the burden voltage, specified in volts per ampere.

Digital Multimeters (DMM or DVOM)

Modern multimeters are often digital due to their accuracy, durability and extra features. In a digital multimeter the signal under test is converted to a voltage and an amplifier with electronically controlled gain preconditions the signal. A digital multimeter displays the quantity measured as a number, which prevents parallax errors.

Modern digital multimeters may have an embedded computer, which provides a wealth of convenience features.

Modern meters may be interfaced with a personal computer by IrDA links, RS-232 connections, USB, or an instrument bus such as IEEE-488. The interface allows the computer to record measurements as they are made. Some DMM's can store measurements and upload them to a computer.

The first digital multimeter was manufactured in 1955 by Non Linear Systems.

Safety

Digital meters are category rated based on their intended application, as set forth by the CEN EN61010 standard. There are four categories:

Category I: used where current levels are low.

Category II: used on residential branch circuits.

Category III: used on permanently installed loads such as distribution panels, motors, and appliance outlets.

Category IV: used on locations where current levels are high, such as service entrances, main panels, and house meters.

Each category also specifies maximum transient voltages for selected measuring ranges in the meter. Category-rated meters also feature protections from over-current faults.

DMM alternatives

A general-purpose DMM is generally considered adequate for measurements at signal levels greater than one millivolt or one milliampere, or below one gigaohm — levels far from the theoretical limits of sensitivity. Other instruments are used for accurate measurements of very small or very large quantities. These include nanovoltmeters, electrometers and picoammeters.
