Elixir Interview Questions: Elixir has a similar deliberation as that of some other programming language for building the conveyed and adaptation to internal failure applications. Aside from that, numerous organizations are additionally utilizing it for web advancement and building inserted frameworks. Because of which there is slight increment popularity of the competitors with Elixir information.
Different organizations are searching for possibilities for the positions like programming engineer, Python engineer, Elixir designer, Elixir full-stack designer, and so on. Along these lines, the hopefuls with information on Elixir out there have an incredible chance to hit a grand slam and fly with high hues.
Prior to finding a vocation, it is compulsory for anybody to break the meeting. It is simple for a possibility to split the meeting in the event that he/she does a total examination and learning of the subject before showing up for the meeting.
Elixir is a functional, concurrent, general-purpose programming language that runs on the Erlang virtual machine. Elixir builds on top of Erlang and shares the same abstractions for building distributed, fault-tolerant applications. Elixir also provides productive tooling and an extensible design.
Elixir Interview Questions: Here we furnish you with a couple of essential and major inquiries that you may experience during the meeting. These inquiries addresses will brush you up with the Elixir nuts and bolts and make you solid at the basics, which numerous selection representatives look for in an applicant showing up for the meeting.
How about we trust that these inquiries help you in breaking the Elixir meet and in getting work. Along these lines, begin for a brilliant future and effective profession ahead. Good luck, people!

What is meant by string interpolation in Elixir?
It is a method of constructing a new string value. The code is normally wrapped with curly braces and the # sign.
What is the use of the crypto module in elixir?
It is used to decrypt project applications using the hashing function and digital signature.
What is the match operator in elixir?

Explain how you can create a map in elixir?

Define the feature of Elixir?
Elixir has many features that attract application developers.
Elixir has the following features:
- Fault of tolerance
- Build tools
- Scalability
- Functional Programming
- Erlang Compatibility
What is elixir Features?
- A language that compiles to bytecode for the Erlang Virtual Machine (BEAM)
- Everything is an expression
- Erlang functions can be called from Elixir without run time impact, due to compilation to Erlang bytecode, and vice versa
- Meta programming allowing direct manipulation of abstract syntax tree (AST)
- Polymorphism via a mechanism called protocols. Like in Clojure, protocols provide a dynamic dispatch mechanism. However, this is not to be confused with multiple dispatch as Elixir protocols dispatch on a single type.
- Support for documentation via Python-like docstrings in the Markdown formatting language
- Shared nothing concurrent programming via message passing (Actor model)
- Emphasis on recursion and higher-order functions instead of side-effect-based looping
- Lightweight concurrency utilizing Erlang’s mechanisms
- Railway oriented programming via the with construct
- Built-in tooling for managing dependencies, code compilation, running tests, formatting code, remote debugging and more
- Lazy and async collections with streams
- Pattern matching[28] to promote assertive code
- Unicode support and UTF-8 strings
