Reverse a Linked List

You're sent a linked list of numbers, but it's been received in the opposite order to what you need. This has happened multiple times now, so you decide to write an algorithm to reverse the lists as they come in. The list you've received is as follows: 7 2 21 6 42 10 Write ...

Array Intersection

As we ease our way into the course, we'll want to start with the basic data structures and their operations. However, don't be fooled how fundamental these things are! Interviewers will often test you on things that are deceptively easy. We saw this in Reverse a String challenges reverse a stri...

Implement a Hash Map

Arrays are amazing for looking up elements at specific indices as all elements in memory are contiguous, allowing for O 1 or constant time lookups. But often we don't, or can't, perform lookups via indices. Hash maps and hash tables are a way around this, enabling us to lookup via keys instead. ...

People at C3.ai Say

This information was sourced from reviews originally posted on Glassdoor.

People love the ceo. i heard it during interviews and i hear it very often. again feels a bit unnatural, but again, hey. . . its not a bad thing

I joined recently and was able to get a feel that the company even after going public has a very start-up mentality and you are surrounded by smart people. Everyone in the company looks like they are on a mission, which is great for the companies future.

You get to work with awesome people in a positive environment that encourages you to do your best and grow in more ways than one. All aspects of the work thus far are more than satisfactory.

I am an experienced engineer, who has worked in a number of other companies before. C3. ai is the first company where I truly enjoy everything, and I can see myself staying here for a long time.
