[6]: 67 Candidates answering questions should consider the use of technology in the present and future, and user scenarios. Some questions involve projects that the candidate has worked on in the past. A coding interview is intended to seek out creative thinkers and those who can adapt their solutions to rapidly changing and dynamic scenarios.

Handling errors in this manner is considered bad practice [1] and an anti-pattern in computer programming. In languages with exception handling support , this practice is called exception swallowing .
Common exceptions include an invalid argument (e.g. value is outside of the domain of a function), [5] an unavailable resource (like a missing file, [6] a network drive error, [7] or out-of-memory errors [8]), or that the routine has detected a normal condition that requires special handling, e.g., attention, end of file. [9]
The implementation of exception handling in programming languages typically involves a fair amount of support from both a code generator and the runtime system accompanying a compiler. (It was the addition of exception handling to C++ that ended the useful lifetime of the original C++ compiler, Cfront. [18]) Two schemes are most common.
Unpropagated updates; e.g. programmer changes "myAdd" but forgets to change "mySubtract", which uses the same algorithm. These errors are mitigated by the Don't Repeat Yourself philosophy. Comments out of date or incorrect: many programmers assume the comments accurately describe the code. Differences between documentation and product.
Off-by-one errors are common in using the C library because it is not consistent with respect to whether one needs to subtract 1 byte – functions like fgets() and strncpy will never write past the length given them (fgets() subtracts 1 itself, and only retrieves (length − 1) bytes), whereas others, like strncat will write past the length given them.
In computer programming, a code smell is any characteristic in the source code of a program that possibly indicates a deeper problem. [1] [2] Determining what is and is not a code smell is subjective, and varies by language, developer, and development methodology. The term was popularized by Kent Beck on WardsWiki in the late 1990s. [3]
