Do you know about the DistinctBy method?
You can grab MoreLinq off of Nuget for pre-.NET6 and it has a DistinctBy implementation that you might be able to use: https://github.com/morelinq/MoreLINQ

Three words.,, => C# Functional Programming is awesome!!! Do you seasoned developers have any war-stories or nightmare stories regarding Functional Programming?
Install "morelinq" 3.3.2 from Nuget: https://www.nuget.org/packages/morelinq You know you got the right one if it has about 37.2 million downloads.

Is there a reason why a WithIndex() extension method isn't apart of the standard library?
If you don't already know about it, I highly recommend checking out the MoreLINQ open source project which adds a bunch of these less common but still occasionally useful extensions to LINQ. They also include an Index method which does exactly what your WithIndex method does, yielding out KeyValuePair entries for each iteration.
- How to remove duplicates from a list, I've tried multiple approaches but with no luck. Can You help me out or point me in the right direction, please. My attempts are in the post

Just had a Senior Technical Interview that was so bad and such a waste of time that I burnt that bridge and burnt it hard. If this is how your company interviews people please stop.
yield return is a significant core piece of the framework. It's the basis of which most deferred execution and LINQ is built upon and any extension one would want to add to LINQ. (for example)

it feels as though the LINQ queries are inferior to simply using the Enumerable extensions, is there something i'm missing?
For a time, I'd say the Query Syntax was comparatively as popular as the Method Syntax. But over the years as LINQ became ubiquitous for working with non-database queries (LINQ-to-Objects) and more users extended them (for example, MoreLinq) the Method Syntax became more popular. I'd say nowadays the Query Syntax is relatively rare to see and perhaps mostly limited to direct database queries or these scenarios like "join" that are easier.

Things I don't like or confused me in C#
If you don't already know about it, take a gander at the MoreLINQ extensions. I don't think it solves this particular problem, but it's a great example of extending LINQ.

LiteDB: A .NET embedded NoSQL database
Before checking this out, people might want to take a look through the issues and pull requests of which there are 500+ and 50+ respectively [1]. I was really optimistic about this project and it was headed in a great direction, but it's not in a production ready state, and it seems that the main guy behind it has decided to move onto other things. It's been about a year since there was any significant activity.
I just mention this because a lot of these little issues might only become more apparent after integrating the db into your project and so it can be a bit annoying. I ended up swapping to Linq2DB [1]. It's something, more or less, similar offering an ORM/LINQ type system as well as the ability to also use direct SQL if desired. But the neat thing is that it also uses a standardized API for the LINQ query language, so you can do things like swap from SQLite to PostgreSQL in one* line of code, so long as you're not using any provider specific extensions.

Flyweight: An ORM for SQLite
I had a positive experience with Linq2db? https://github.com/linq2db/linq2db
I mention because I had something of the opposite experience with it. It not only ended up yielding the correct queries, but I saw a significant increase in performance. And the neat thing about it, beyond ORM and linq-to-sql, is a common interface amongst providers - so you can do things like swap from SQLite to Postgres with 1 line* of code, so long as you're not using provider specific extensions.

.NET 6 - ORM vs Stored Procedures - Azure Functions + SQL Databases
Temporary tables are covered by linq2db. But better to show Stored Proc maybe your final query just needs several CTE which also supported by linq2db.
