United StatesPosted Dec 2025 · Candidate report, summarized by Dataford

My process was terribly long and the first part set a negative tone.

It started with an OA that lasted roughly one and a half to two hours. Although it had a technical section, it wasn’t coding at all—it felt like random math brain teasers and behavioral-style prompts mixed together.

After that, I did a one-way interview that felt more okay than the assessment. The overall difficulty felt easy-to-average for me, but the OA wasted time and didn’t align with what “technical” usually means.

I didn’t receive an offer. My reflection was that the interviews after the OA were fine, but the initial format and length made the whole process feel inefficient.
