Q:

Tell us about a time when you missed a significant deadline

Answer

Tell us about a time when you missed a deadline.


(or)


Let's discuss a time when you missed a significant deadline.


If you answer something like "You never missed a deadline". Most interviewers will immediately conclude you are not experienced and may also feel you are lying. 


Approach - It is absolutely necessary to accept that you have missed a deadline and give reasons how you resolved and what you learned from it. This will demonstrate your experience.


You could say in one of the first projects earlier in your career you missed an important deadline and made the boss very upset. It was a great learning experience and after doing some introspection, you realized, you could have done better planning, prioritization and communication. Now, you use special tools, processes and methods to address these issues. Now your team, colleagues and management are always up to date so no surprises arise on meeting deadlines. 


Below are few things you may emphasize on in your response...


Effective planning


Procedural Improvements


Better Prioritization


Open communication


Better Status reporting

Q:

How is final different from finally and finalize()?

Answer final is a modifier which can be applied to a class or a method or a variable. final class can't be inherited, final method can't be overridden and final variable can't be changed.

finally is an exception handling code section which gets executed whether an exception is raised or not by the try block code segment.

finalize() is a method of Object class which will be executed by the JVM just before garbage collecting object to give a final chance for resource releasing activity.

Q:

For printing out strings, there are echo, print and printf. Explain the differences.

Answer - echo is the most primitive of them, and just outputs the contents following the construct to the screen. print is also a construct (so parentheses are optional when calling it), but it returns TRUE on successful output and FALSE if it was unable to print out the string. However, you can pass multiple parameters to echo, like:

and it will output the string "Welcome to TechInterviews!" print does not take multiple parameters. It is also generally argued that echo is faster, but usually the speed advantage is negligible, and might not be there for future versions of PHP. printf is a function, not a construct, and allows such advantages as formatted output, but it’s the slowest way to print out data out of echo, print and printf.

Q:

What’s the difference between include and require?

Answer It’s how they handle failures. If the file is not found by require(), it will cause a fatal error and halt the execution of the script. If the file is not found by include(), a warning will be issued, but execution will continue.
