Interviewing Senior Level PHP Programmers

This post is intended to educate interviewers and interviewees on what I ask with my programming team to qualify candidates for hiring high level PHP developers.

PHP SECTION

Question #1:

We draw the following URL on a while board and have the candidate identify each part of the URL.  Keep in mind, we start very BASIC to get them comfortable white boarding and then slowly get more difficult.

https://www.example.com/jams/jellies/13

We ask them to identify the SSL piece of the URL, the domain name, the model, view, controller and action.  For any senior level developer, if you ask them what MVC stands for and they say anything other than model, view, controller….you should be wary.

 Question #2:

We ask the candidate to write a function that passes two variables and returns a string.  Again, this is very basic and if they are unable to do this, or take more than 5 minutes to do so you may not be dealing with a senior level developer.

Question #3:

Setup a class called Jams that inherits Jellies.

Question #4:

Please define in your terms what refactoring means?

Question #5:

Write a getter and a setter method that takes in a number with a  decimal and outputs a number without a decimal.

Question #6 (fizz buzz test):

Using php code (not looking for exact syntax) please do the following:

Write a script that echo’s the #’s 1 – 100.

For #’s that are a multiple of 3, print fizz instead of the number

For #’s that are a multiple of 5, print buzz instead of the number

For #’s that are a multiple of 3 and 5, print fizzbuzz instead of the number

This question will give you an in depth look into there problem solving skills, reasoning and there approach to coding while not in front of there computer.

HTML/CSS SECTION:

Question #1:

We draw a basic layout of a website that has a container div centered on a page, a header, navigation, content and footer div inside the container and have the candidate code the layout in html and css on the whiteboard.  We realize there is lots of ways to code layouts, we are just looking to make sure they understand cross browser compliance, standards and aren’t using tables.

Question #2:

What is the proper way to write a break tag that will validate in transitional doc type.

JQUERY/AJAX

Question #1:

Write a basic jquery selector.  Also write a small block of jquery that adds two numbers together and appends the result to a div called total.

Question #2:

Define AJAX and how you have used it in a web application.

GENERAL QUESTIONS:

We then ask them what their strengths are and what their weaknesses are.  Depending on how they answer this question we have the white board something tailored to there strength and white board something tailored to there weakness….to see how weak they are and how strong they are according to us.

This all generally takes about an hour with limited amounts of wasted time.  We are looking for programmers that can program from scratch (not looking for exact syntax but more for deficient/clean decision making.

Web Design that is decidedly conscious of such needs can be extended to meet the needs of such users. The push for greater web site accessibility is becoming more and more main stream. Already, many major websites have improved their accessibility to those with disabilities, and are striving to do even more.

Arizona Mobile Website Design
Website Design For Mobile Applications

It used to be the rage to have a cell phone. These days a typical persons cell phone is much more than a phone. It can make calls, send and receive text messages, send and receive email, access the internet, play music, take photos, and more. Smart phones with all these capabilities are really small computers, and remarkably powerful ones at that.

A majority of the special features found on smart phones are internet dependent. They cannot function on the phone alone. As a result, the internet community has to adjust to meet the demands of mobile web access. This has significant implications for entities such as businesses or non-profit organizations that use the web for advertisement or commerce. Arizona web developers have to develop a new set of skills to provide quality web design for the mobile web. Smart phone users are quickly learning what sites are mobile web friendly, and those sites are winning the attention of mobile users.

When it comes to creating a smart phone friendly design, Arizona web designers are definitely more restricted than they are for computer or tablet designs. Mobile web design is restricted by mobile browsers and by the size of mobile screens. As a result, mobile web pages must be decidedly more compact that traditional pages. The creativity of Arizona Web Design professionals is being stretched to new limits to adapt to the issues that mobile web design demands. Just as with regular web design, mobile web design needs not only to be functional, but attractive and user-friendly as well.

Arizona web developers will have to learn and use a new set of skills when designing for mobile devices. It just wont work well to use the same construction and structure for a mobile device as they would for a desk or laptop computer. Wireless application protocol must be used while browsing on mobile phones. There are Arizona web design guidelines for developers to adhere to. While these guidelines need to be strictly followed, they will become second nature in time, and need not hamper a designers ability to use creativity and artfulness. While developers will probably be required to strip down the designs that are currently be used, they can now find standard designs to work from that are wireless application protocol (WAP) compatible.

Often, developers will be asked to design a version of an existing website that is WAP compatible. The best way to build such a website is to simply modify the existing site or add-on to it to create compatibility. Several changes will be required in order to provide a single website that is both full-browser and WAP compatible. Alterations in layout, construction, and design will all be requisite. Once a mobile-friendly design has been completed, browser sensing can be implemented to detect mobile access and activate the mobile version of the website for mobile users.

New technology always stretches developers to new limits. Mobile device internet users will expect and demand web designs suited for use on their devices that are compatible with wireless application protocol. While users probably won’t understand the complications of their demands, developers will have to rise to the occasion. As with all things technological, doing so will become second nature in a short period of time.

Companies that kept up with the technological curve had a continued opportunity for growth. Those that did not make the jump to the internet felt the effects and may not have been able to keep up with competitors that were online.

The same phenomenon is occurring once again, only this time with mobile internet access. More and more consumers are using handheld devices to access the internet. From their mobile phones they are researching and purchasing. Traditional Phoenix Web Design for lap and desktop computers is not compatible with internet capable hand held devices. Websites that are not wireless access protocol (WAP) compatible are difficult if not impossible to browse on a mobile device. As a result, online businesses are under pressure to create quality WAP compatible sites in order to keep the attention of mobile consumers.

There are a number of mobile Phoenix Web Design service features that can keep your business in the mobile sights of key consumers.
