Helm.ai interview questions

I was interviewed in Feb 2024. The entire process took 4 weeks. 1. Recruiter call 2. 1 hr Tech screen (coding question. not leetcode style) Once tech screen was successful, I was invited for virtual onsite 1. 1hr coding interview (Graph question) 2. 1hr python debugging session. 3. ML System design. 4. ML & Math test 5. Project discussion All the interviewers were really nice and genuine. The ML and Math test was unusual(The person conducting this interview was seemingly uninterested.) The test was about knowledge of ML and calculus. Not sure if you need calculus to effectively do your job.

The initial phone screen involved verbal questions about MNIST data, in particular data augmentation. Don't waste your time studying ML for the technical screen. My interviewer was very curt and acted like interviewing me was an inconvenience.
