      Senior Software Engineer Interview

      Application

      I applied through a recruiter. The process took 2 weeks. I interviewed at C3 AI in Jun 2024

      Interview

      Astounding waste of one's time. Don't bother interviewing. TL;DR: I interviewed, at the last round they told me about fit mismatch despite not really screening for the fit (only DSA rounds), wasted my time. I did not apply to this position but I might have been in the pipeline because I had applied to other internships before for which they got back to me to schedule interviews, but after providing my availability never got back to me. 😂 So I received an email to complete a Hackerrank test first. In the Hackerrank test solved 2 LC easy-medium questions. Then they scheduled an interview with the hiring manager about discussing the role, my resume, experience and interests. The hiring manager then moved me to the technical rounds which were scheduled for 2 weeks later. The recruiter I was paired with at C3 AI was so unresponsive I had to email hr@c3.ai to get a response from her on what the technical rounds are going to be on (DSA rounds or system design or ML) because there was no information other than it being "technical rounds". The technical rounds were 3 back to back elimination rounds but scheduled together. Each round was a mixture of some resume questions in the beginning followed by 1- 2 LC easy-medium questions. The interviewers in the first 2 rounds did tell me on seeing my resume that there is no ML in this role but mostly abstractions on top of ML models (because I mostly have a MLE experience, only had a short SDE stint). I told them that I am aware of this and am still interested, as my interview with the hiring manager clarified everything for me and he also moved me to future rounds knowing my experience. I spoke of some projects and solved the questions in both rounds, but at the beginning of the third round--which was with a tech lead--he let me know that he spoke with the other interviewers and that they would not be proceeding further. On asking for feedback he said that there is a mismatch of role and fit. It really pissed me off as despite knowing my experience and wasting 2 hours of my time, and not really screening with any software rounds other than general DSA, they would come back to say your experience seems to not match. They already had that information, and if they just wanted full stack developers they should screen for it. Massive waste of time. Even had I gotten through I would really be hard pressed to accept it knowing such a gross mismanagement and lack of respect for a interviewee's time.

      Interview questions [1]

      Question 1

      Hackerrank 2 LC easy-medium questions. 1. Go from source to target position on a board, only valid moves are (x, y) -> (x+y, y) or (x,y) -> (x, x+y) 2. Given a string and integer k remove all instances of k consecutive equal characters to compress string to smallest possible word With hiring manager and beginning of technical rounds: asked questions about resume, experience, tech stack, challenges faced in work/projects Technical round coding questions: 1st round: given a binary tree find a path between any 2 nodes 2nd round: LC two sum: given an array and target sum find the indices of the elements that add upto target. Then asked to optimize solution to O(1) space.

      I interviewed at C3 AI

      Interview

      The process included a Hiring Manager screen followed by two coding rounds and one System Design session, with behavioral questions integrated throughout. While the initial rounds were standard, the System Design experience was disappointing. The interviewer appeared to have a preconceived notion of the "only" acceptable solution and was dismissive of alternative architectural approaches. It felt less like a collaborative technical discussion and more like a test to see if I could guess his specific implementation preference. This lack of objectivity made the round feel unproductive.

      Application

      I interviewed at C3 AI (Redwood City, CA)

      Interview

      They asked a LeetCode-style interview question from a graph as the first round. Then there were three other coding interviews. I was surprised there was no design question. This was followed up by the manager's behavior interview, the culture seemed very intense and sort of misdirected engineering leadership.

      Easy interview

      Application

      I applied online. The process took 3 months. I interviewed at C3 AI (Redwood City, CA) in Jun 2025

      Interview

      Interview Process: What began as a fairly standard interview process quickly spiraled into an exhausting, opaque, and ultimately disheartening experience. Here's what I went through: Hiring Manager Chat – Warm and engaging. Set a hopeful tone. Three Technical Interviews – Two rounds of algorithms, one OOP design. Challenging but fair. Behavioral Interview – In-depth and thoughtful. Reinforced mutual interest. Two References Provided – Both spoke directly to my skills, impact, and character. Additional Managerial Reference Required – An unexpected ask, but I complied and provided a strong FAANG reference. Verbal Offer Extended – Encouraging conversation; I was told a written offer was forthcoming and advised to pause other interviews. Negotiation Phase – Discussed comp and start date. Awaited the offer letter. Sudden Onsite “Team Fit” Round – A surprise panel interview that felt more like a stress test than genuine team matching. Another Reference Request – This time demanding a specific manager from a prior employer I no longer had access to. I was told, “This is the final step.” I tracked someone down and booked it. Final Outcome – The morning of that 4th reference’s scheduled call, I was informed: “We’ve decided to pursue other candidates whose experience aligns more closely with our current needs.” Red Flags: Lack of Transparency: The process was never clearly scoped. Steps were added after a verbal offer. Moving Goalposts: Every hurdle I cleared was followed by a new one — culminating in four separate references. Unprofessionalism: Encouraging a candidate to pause other interviews based on a verbal offer, only to ghost them, is unacceptable. Power Imbalance: The process felt increasingly like a test of endurance rather than an honest evaluation of fit. It sends a concerning signal about the company culture. Advice to Candidates: Approach this process with caution. Do not pause your job search, even if you’re told an offer is coming. Be prepared for sudden changes, unclear expectations, and a potentially demoralizing experience. Advice to C3.ai: If you want to hire top-tier talent, treat them with the same respect, transparency, and integrity you claim to value. A verbal offer is not a placeholder — it’s a commitment with real-world consequences. Candidates deserve better.
