IOS Interview Questions : Interview Questions

Mainly iOS convention houses lean to have one or two skilled developers, besides a huge number of junior people. It is also frequent to organize anyone with more than 3 years of experience job with Cocoa to as 'senior'. At Black Pixel, nearly all of the developers in the staff have 7 to 10 years of Cocoa experience, and several of them are ex-Apple product engineer. Only some 'junior' developers would be measured very senior somewhere else.

It's decisive that the people take on are good sufficient to continue with the rest of the team. We are living at a fast pace, and a fresh hire that can't keep up will make things tougher for their people we're working with. It is not actually just right to throw someone into the bottomless end of the pool without giving them some plan of how tough they are going to have to work in sort to grasp up with everybody else.
This is not at all complete list of questions, but it is good enough to get an idea about what you are going to asked:
·         How will you work with asynchronous networking?
·         Did you work with multi threaded Core Data? Which approach you used and how was it?
·         Did you work with Core Animation? Give some details about kind of animations?
·         Do you know something about Core Graphics? If yes, what kind of graphics do you know about?
·        Did you ever packed any demonstrated issues against Apple frameworks on radar? Describe some
·         Differentiate and compare between NSNotification vs KVO? When will you use one or another also describe some allusion of using them.
·         Did you ever work with NSOperationQueue, for which purpose you used it?
·         Give some details about Core Text Experience
·         How will you use NSURLConnection on background thread?
·         On which things you should be careful about when you are working with blocks?
·         Did you ever made any custom frameworks or libraries?
·         Which is your preferred method for working on application in parallel with a library?

On-the-job training - Training the New Employees at the Workplace

Fresh graduates or interns in their last year of bachelors, hired often have little to no work experience when they are called for interviews and taken into the team. It is because for most of them, it’s their very first interview and job and since they are never worked before, they are new to the office environment and how things work in a company and how the skills learnt in the bachelors are applied in the practical life. Usually, employees are given training on the job and assessed over a certain time period specified depending on the company, so that the company can know if the hired employee can hold on to the real-time pressures and be a part of the team, delivering quality service. Some companies however, cover the training during the internship period of the employee, and if they manage show good enough skills, they are offered a permanent job. That ensures that the employee is already prepared when he/she starts working for the company. But what if you’re left wit...
