What do you mean by Explicit Interface Implimentation? What’s Interface Mapping?
A class that implements an interface can explicitly implement a member of that interface. When a member is explicitly implemented, it cannot be accessed through a class instance, but only through an instance of the interface
When class implement interface user mandatory needs to specify interface method body. Such implementation is called as Exlicit
implementation. All the signature of interface API must be compatible with interface API. Dervice class can also define their
own API.
1: interface I1
2: {
3: void someMethod();
4: }
5: Interface I1
6: {
7: void someMethod();
8: }
9:
10: class someClass:I1 I2
11: {
12: void I1.someMethod()
13: {
14: //This is called explicit implementation as i am telling the compiler to implement someMethod of interface I1
15: }
16: void I2.someMethod()
17: {
18: //This is called explicit implementation of someMethod of I2 interface
19: }
20: }
Notes, 4 Jobs for Daredevils
Hotshot Crew Member
The job: Hotshot crew members exceed the typical training, experience and physical fitness of the average firefighter and specialize in fighting the toughest part of a wildland fire.
The risk: Pretty high. In addition to suppressing fires, which can entail flying to remote locations for weeks at a time with limited resources and heavy equipment, they often perform dangerous search and rescue missions.
The pay: $36,474/year and $41,829 with benefits and bonuses.
Hazmat Diver
The job: Hazmat divers swim through sewers, inside nuclear reactors, through toxic spills on coasts, and in waterways to perform cleanup of chemical spills, and repair and maintain pipelines.
The risk: Pretty high. In order to be exposed to any number of toxic materials and bacteria, these workers need only a minor breach in their drysuits, which takes skill to avoid considering the random shards of glass or syringes that may be found on the job.
The pay: $31,183/year and $38,189 with benefits and bonuses.
Rodeo Clown
The job: Rodeo clowns entertain the crowd at rodeos between sets and, more importantly, protect cowboys from getting trampled by an angry bull during sets. Rodeo clowns are charged with the responsibility of distracting the bull long enough for the cowboys can get back on their feet and back to safety.
The risk: High. In order to protect a cowboy from getting trampled, these bullfighters risk getting trampled themselves. To survive their job, these clowns must have nerves of steel and be faster than a speeding bull.
The pay: $31,054/year and $37,480 with benefits and bonuses.
Stunt Performer
The job: Stunt performers stand in for actors on film sets, performing specialized -- and often dangerous -- stunts.
The risk: Significant. The stunts often involve jumping from high buildings, driving and crashing automobiles and even catching on fire; however, strategic timing and prop use help to minimize these dangers.
The pay: $42,539/year and $53,026 with benefits and bonuses.
Interview Tips: 3 Job Search Mishaps
Despite your best efforts, there are some mistakes you simply can't recover from, such as submitting a résumé and cover letter addressed to the wrong employer. But other errors do not necessarily spell doom for you.
Following are common mistakes job seekers make and tactics that will give you a fighting chance to recover:
Mishap No. 1: You arrive too early
Though it may not seem like a terrible offense, being very early for an interview can create a poor first impression. If you're camped out in the reception area half an hour before your meeting, the hiring manager may not appreciate the pressure to see you earlier than expected. Wait in your car or outside the building if you arrive more than 15 minutes before an interview and use the time to prepare. Then, head to the restroom to check your appearance one last time. Aim to be in the company's lobby about five minutes early.
Mishap No. 2: You lowball yourself
What happens when a hiring manager requests your salary requirements, and you later find that you asked for too little compensation? Be honest and act quickly. Tell the hiring manager that you've done additional research and feel the figure you quoted falls below market trends. Be sure to reference any supporting documentation, such as salary surveys, that help you make a case for higher starting pay. Employers are often willing to renegotiate salary before an offer is accepted if an error like this is made because they want new employees to feel valued from day one. However, in the future, you should always do your compensation research before you begin the interview process.
Mishap No. 3: You flub an interview question
"Why are manhole covers round?" Even if you're not asked a brainteaser like this, you may stumble when answering a question posed by the hiring manager. In this situation, don't panic. If you find yourself rambling or grasping for words, pause to think more about your answer. The interviewer will understand if you need some time to formulate a response. If you bombed a question earlier in the meeting, only to think of the perfect response later, ask the hiring manager if you can revisit the question. You'll demonstrate your ability to think on your feet and have the opportunity to get your message across.
5 Types of Interviewers
To give you a little extra help, here is a list of 5 types of interviewers you might encounter and how to deal with them.
1. The rule follower
What to expect: Every interviewing tip you've ever been told. Just like some students never imagine skipping a day of school or not doing homework, some interviewers can't imagine going outside of traditional business interviewing protocol. Boring questions and a stoic demeanor are this interviewer's best friend.
What to do: Be the best interviewee you can be. Do you know what your biggest weakness is? Do you know how to give the perfect handshake? Do you plan on wearing a conservative shirt under your jacket? You had better, because these by-the-book practices will earn you high marks.
2. The mafia
What to expect: An intimidating group. Every group interview is an ordeal. The interviewers might be lovely, horrible or a mix, but you still have several sets of eyes staring at you.
What to do: Try to relax. That seems like impossible advice, but it's the best approach. When you have multiple interviewers, you will see several types of interviewers, so you can't try to please everyone. Try to be yourself and find the interviewers that seem the most responsive to you. When you see someone nodding in agreement or maintaining eye contact, you'll feel more at ease and the nerves will begin to disappear.
3. The joker
What to expect: A comedy routine. Some interviewers have such a good sense of humor that they can't shut it off even when they need to. You'll answer a question and you'll receive a sarcastic comment or a funny aside. This approach isn't inherently bad, but it can confuse you because you're not sure if the interview has even begun.
What to do: After a few minutes, you'll realize that your interviewer is a joker. If this personality bugs you, you probably won't like working for the company. If it doesn't bother you too much, then try to play along. Joke back and show that you have a personality. For some interviewers, your résumé proved your qualification; the interview is their chance to see if you fit in with the gang.
4. Your best friend
What to expect: Too much of everything. You walk in the door and the handshake is a little too enthusiastic. The smile is too wide. The conversation is too personal. It's all just too much. This interviewer treats you like a best friend, which is nice, but this style is unnerving because you want to be relaxed without forgetting that you are still on an interview.
What to do: Take this approach as a cue that you can be a little less rigid in the interview because the best friend doesn't want an uptight employee. Just remind yourself that the interviewer can be more casual than you because he isn't the one interviewing for the job. Show the interviewer that you're relaxed, but stay professional and don't act like you're actually good friends -- stories about wild parties and your personal life don't belong in the conversation.
5. The interrogator
What to expect: Question after question after question. The interrogator doesn't come to the interview ready for conversation. He has a list of questions to fire off and you had better be ready to answer them. Don't expect to receive a lot of helpful feedback to gauge how you're doing. Just expect more questions.
What to do: Watch episodes of "Law & Order" to prepare. You're going to feel defensive the entire time and might walk away from the interview feeling as if you did something wrong. Once you realize that your interviewer is going to lambaste you with questions, just focus on answering them and don't obsess over reading his reaction. You can try to initiate conversation with a few of your answers, but don't be surprised if those efforts fail. This interviewer wants to hear your answers and see how you handle yourself, so staying calm is the best approach you can take.
Interview Question: The one who has better things to do
An interviewer checking her e-mail, looking at you but not paying any attention to what you say. Some people are forced to participate in the interview process even if they have no interest in doing it, so don't take it personally.
What to do: Answer the questions and be friendly. Try to hold conversations with this distracted interviewer and hope you can win her over -- hey, it can't hurt to have someone who likes you. But this interviewer either made up her mind before she walked into the room or doesn't intend to give much feedback about you, so do your best but don't take her disinterest personally.
What is the use of serializable keyword in C#?
Marking a class with the key word [Serializable] at the top ensures that the object can be serialized in an XML format primarily for data exchange between disparate systems. Also, this is required if this object is going to be inherited by other objects which needs to be serialized downstream.
Serializable is a concept of converting your user define type i.e. class into bytes. Serializing object into bytes help for ease in transporting data within network or machines. .Net also provides support to desializing
We can do Serializing in following ways:
i. XmlSerializer.
ii. Soap Formatter and Binary formatter.
AutoPostBack Property in asp.net
There is Cancel button and OK button on page. When we click Cancel button it skips all validation controls and goes to next page.
(a)Page AutoPostback of Cancel is True.
(b)Page AutoPostback of Cancel is False.
(c)Page AutoPostback of OK is True.
(d)Page AutoPostback of OK is False.
Which option is correct?
Answers: A button control does not have AutoPostBack property it has click event. so once you click on cancel and if its CausesValidation Property is false it will skips all validations and if it is true it will validate the controls on the page.
AutoPostBack property is for say DropDown textbox etc... whnever you change/enter value/keyed some caharcter in textbox or change your selection in drop down postback will happen if that control's is AutoPostBack property is true depending on that postback you can fill values or set some values for other controls or you can do somevalidation against enterd or selcted values.
e.g. say tehre are 2 drop down. DropDown1 and DropDown2
DropDown2 is currently holding states of US country as in DropDown1 you have selcted US. Now you want to fill DropDown2 with state value of India.
Now if
DropDown1.AutopostBack True;
and you change DropDown1's value from Us to India.
Page will post back to server and you can fill DropDown2 with Indian States.
Project Management Interview Questions
How do you decide what gets top priority when scheduling your time?
Paid work first! If there is a client waiting for a report or a letter, this takes priority over any other task I have waiting for me.
What are the 4 stages of team development?
1.Forming
2.Storming
3.Norming
4.Performing
Which process is applied to break down the project into smaller, more manageable elements?
Scope Definition is incorrect answer according to A Guide to the Project Management Body of Knowledge (PMBOK) published by PMI. At least the 3rd edition of it which I have. But if I recall it right, it has not been changed in the last draft of the 4th edition I saw.
The process is called Create Work Breakdown Structure (WBS) and it is performed to subdivide the major project deliverables and project work into smaller and more manageable components. The output of this processs is the WBS which represents all work that the team has to perform. See Section 5.3 in the 3rd edition.
