Q34 What Is An Event Bubbling In Javascript
Event bubbling is a way of event propagation in the HTML DOM API, when an event occurs in an element inside another element, and both elements have registered a handle for that event. With bubbling, the event is first captured and handled by the innermost element and then propagated to outer elements. The execution starts from that event and goes to its parent element. Then the execution passes to its parent element and so on till the body element.
What To Expect In A Front
Whether you will have your interview onsite at the companys premises or remotely depends on the companys policies. Once your interview is set you will be notified via email on the next step. Be sure to ask your recruiters on the format of the interview, whether a whiteboard or an online text editor like CoderPad will be involved, and what topics to focus on for the technical aspect so that you can well prepare yourself.
Most tech companies prefer having a remote interview the first time they are interacting with a candidate. There are a variety of conferencing applications that come in handy to facilitate a remote interview session.
The interviewer will inform you about which one they plan to use during the interview. They include Zoom, Skype, , TeamViewer, WebEx, Join.me, GoToMeeting, and Apache OpenMeetings.
In case the company decides on an onsite interview, then you will be appropriately informed. You might be required to do a code mockup to test your skills. Its preferable to carry your own laptop which you are used to working with and have already set up your development environment to avoid panics.
Q30 What Is The Difference Between Undeclared & Undefined
Undeclared variables are those that do not exist in a program and are not declared. If the program tries to read the value of an undeclared variable, then a runtime error is encountered. Undefined variables are those that are declared in the program but have not been given any value. If the program tries to read the value of an undefined variable, an undefined value is returned.

You Want It You Sweat It
So I had made up my mind. I was going to apply to Toptal. Knowing I wasn’t good enough when it comes to algorithms, I decided to study for 3 months, while doing some minor freelance work. For 3 freaking months, every freaking day, I woke up early in the morning and studied algorithms for 3 hours. I ordered Cracking the coding interview from Amazon and used it as my study book – can’t recommend it enough. It’s surely more than what you need to get accepted into top remote work marketplaces, so that’s actually a good thing. I also completed 42 coding challenges in HackerRank in the span of these 3 months and more than 15 challenges from Interview Cake. If you’re dead serious about something, you should be working your ass off for it. The Toptal interview can be quite tough in algorithm theory, so be well prepared and you’ll be ready to go.
Round : Project Discussion
After you pass round 3, you will receive instructions on a project to complete and discuss. Your first task will be to estimate how much time you need to finish the project and commit to a date to deliver it. This makes total sense to me because as a freelancer you will be doing it all the time. I appreciated it. After the commitment, you schedule a meeting with another interviewer for the final discussion.
In the meanwhile, you also receive access to a private git repo on which you push code. The project itself should be usual business and it is probably the easiest part, surely the one that feels closer to your normal job. Anyway, that said, this is not a trivial project. The logic itself is complex enough to show your skills and just hacking something up will not cut it. Put into practice all the good engineering principles you learned over the years and you will be fine. In my case, I also delivered some extras which were received as a good sign.
The discussion itself is not really difficult, but keep in mind you are in an interview. Be ready to justify your decisions and to explain the architecture of your project. This part is what you should be doing every day at work so I will not elaborate further. After the discussion, you set your final rates. Finally, after the interview, you will receive a link to a new shiny profile to fill out. Congratulations you are in!

Round : Communication Skills
The first interview was fairly easy for me, perhaps because English has become my main language. I would recommend being at least at the B2 level of the CEFR and C1 is even better. That said, keep in mind that English is not the only point, your online presence such as a blog or you open source contributions do matter. They also try to gauge your motivation and enthusiasm and the reasons behind your application. I was also asked my rates, although the number that matters is the one you give in the fourth interview. All in all, a typical HR interview, so prepare accordingly.

Q28 What Is The Difference Between The Operators ==& ===
The main difference between == and === operator is that formerly compares variable by making type correction e.g. if you compare a number with a string with numeric literal, == allows that, but === doesnt allow that, because it not only checks the value but also type of two variable, if two variables are not of the same type === return false, while == return true.

Local Storage The data is not sent back to the server for every HTTP request reducing the amount of traffic between client and server. It will stay until it is manually cleared through settings or program.
Session Storage It is similar to local storage the only difference is while data stored in local storage has no expiration time, data stored in session storage gets cleared when the page session ends. Session Storage will leave when the browser is closed.

Technical: What Is Your Process For Auditing Reports That You Have Delegated To Other Team Members How Do You Ensure Their Accuracy
An enlightening answer is one that stresses the need to delegate and empower other team members but where there are suitable checks and balances that are in place. From a technical perspective, the use of control sheets in spreadsheets to organize assumptions together and precedent/dependent formula auditing are direct examples of actionable processes.

Cool But Why Go Through All This Hassle
I currently work at the gig I got from CrossOver. Sadly, I haven’t found any time to take at least an hourly job from Toptal, but I hope I get to find some spare hours in the future to do so. I haven’t been able to take any of the offers from BairesDev either. But, the bottom line is, I can’t be happier about my life right now. I get to do what I love for a living , within a truly world-class team and a pretty inspiring manager, I don’t have to commute anywhere and I work from home. I manage my time, I can complete my 40 hours of work anytime between Monday and Sunday, and get paid every freaking week. I know you might be thinking yeah, cool, lovely, but show me the money.
Update 2020: I enjoyed working on CrossOver for over 2 years. Then I switched to Toptal and I’ve been working there for 1.5 years now.
I won’t go into details about my current pay rate, but the salary I’m getting right now brutally exceeds my expectations and surpasses by 4 times the highest wage I was offered as a senior engineer in a pretty well renowned local company. Again, this is not to brag about a damn here, but just to open your eyes to the number of great opportunities lying around out there.

What Is The First Job Interview
The first job interview is the opportunity for you to meet with an interviewer about receiving an offer for your first job. Generally, you’ll apply to jobs in high school, but this step can also occur when you’re in college as well. During this stage, the employer is looking to narrow down the number of qualified candidates that can move ahead to the next stage.
You should expect to hear general questions about your background and interests, and you’ll need to make the case on why you’re the right fit for the position. You want to make sure that you answer the interviewer’s questions clearly and concisely to give you an advantage in moving onto the next step of the process.
Behavioral: Elaborate On Your Process For Prioritizing Work

I have recently passed the screening process on my second attempt and thought of sharing my experience. The screening process is 4 step and its definitely not easy to get into the network. I will try to explain the interview process and how things work later.
Screening process to join the network
Getting jobs
The first thing you do after joining Toptal is building your public profile. Toptal helps you in this process. You need to add you work experience, portfolios, skills and achievements. Once the profile is reviewed and active, you can browse for opportunities in the jobs feed and apply for jobs. Yes, you can apply for jobs in any technology. Toptal then forwards your profile to the client if it finds you suitable to be a match to the requirements.
Getting into the network is tough and also it takes a time to start bagging projects after clearing the process. But as you keep working, the profile builds up and it gets easier to get jobs. The toptal community is very active and helps you in being a better programmer. Overall, its worth a shot and I would recommend you to give it a try. All the best. Cheers.
Can You Describe What Scope Is In Angular
The interviewer may be gauging your understanding of how models are developed within Angular with this question. Try to give an example of how you applied this concept in your past job.
Example:“Scope in Angular is just an object that represents the whole application model. Scope also refers to the execution context of Angular expressions and is usually ordered within a hierarchy that can resemble the DOM, or document object model, application structure. I’ve applied scope in some of my past projects to monitor expressions and events.”
