> python is the most practical language for doing interview questions, because interviews are heavily time-constrained and python allows the developer to go from idea to implementation in the shortest amount of time.

i'm not sure if python is the best, but it's a very strong choice. python also has a lot of built in data structures that are relatively non-broken and highly useful for the archetypical algorithm-prototyping interview questions

e.g. if you are using a language that only lets you use strings or ints as keys for dicts/hashmaps - instead of say letting you use immutable compound values as keys, or a language that doesnt give you set data-structures which support basic set operations (contains, equal, subset, superset, intersect, union, etc), or a language that requires you to write a paragraph of OOP-boilerplate to encode e.g. a list of pairs of values, you're making life harder for yourself than necessary.

also, i claim without evidence that prolonged and continuous exposure to working with languages that dont offer sensible data structures, or only offer broken data structures, may over time hamper your ability to think and problem solve clearly.
