Worst interview experience I ever had!
Had seen some very very bad reviews about c3.ai interview processes before, but had thought they could not be that bad.
With the worst experience I just had, I now truly believe those bad reviews on C3 AI are so true.
A so-called customer-facing company was so unprofessional, and they could schedule a few interview meetings back to back, but cancel the scheduled meetings at will in the middle of the interviewing process, which is literally like bullying the candidates with no respect at all.
What kind of consultant company it is? What kind of customer-facing company it is?
How can anyone trust a company that acts like a bully to the people who were invited for an interview by this company?
Plus, unlike all other tech companies, this company does not allow remort work and requires their employee to work in the office together without masks.
Don't respect their candidates and don't care about their employee's health, will this company really care about what they do and their customers? I probably will give them the biggest question mark. Maybe only care about their revenue and profit.
Moreover, on their website, they feel proud of their hiring process and encourage other companies to follow their way: " We screened most of these candidates based on the resume and technical tests, interviewed nearly 400 candidates, and hired 17. Most organizations seeking to build up technical AI/ML talent should expect a similar recruiting funnel. "
What a joke!
If someone likes to be insulted with no respect, then go to interviews with this company.
1. Online assessment- includes basic ML fundamentals like assumptions of linear regression, random forests, etc
2. 3 technical rounds- problem solving (data science case study), ML round (discuss ML projects and ML deep dive based on specific hypothetical scenarios on how to approach a problem, coding round (DSA)

Trees, stack and queue questions, time series problem
Applied on Nov 4 and got the online assessment on Nov 6. I passed the assessment and got the email from recruiter on scheduling the interview rounds. I emailed the recruiter with a question, did not receive a response and instead got an email that the hiring needs have changed and they will not be moving forward. Weird.

Envié una solicitud electrónica. El proceso duró 2 semanas. Acudí a una entrevista en C3 AI (Redwood City, CA) en dic 2024
Entrevista
I applied online and got the recruiter call within a Week. Got the coding assessment in the evening after the recruiter call and the assessment had some normal ML questions with 2 coding questions based on Data Science.
Then they scheduled the behavioral round (technical walkthrough round) with the senior manager and asked about my experience and resume walkthrough. There were some tough questions on Reinforcement Learning and LLMs. Cleared the round.
Later they scheduled 3 back-to-back technical rounds (2 technical, 1 coding). 1st Technical: Basic ML, Reinforcement Learning, RAG, LLM; 2nd Technical: ML System Engineering Scenario based question; 3rd Coding: 2 codes with Leetcode Semi-Hard and Hard difficulties. All went well but I got rejected after the 3 round without any particular reasoning and received an auto-generated rejection email.
There is a really High Bar that is set to get into this company and mostly they consider PhD candidates with relevant research and experience.
