I applied through a recruiter. The process took 1 week. I interviewed at Blink Ops (Tel Aviv-Yafo) in Jun 2025
Interview
Had a regular phone interview followed by a first round on Zoom. Honestly, the interviewer didn’t seem too interested in hearing about me. His vibe was pretty off — not very engaging, didn’t create much of a conversation. It felt like he just wanted to get through the coding and design questions.
The coding part was a fairly easy LeetCode-style question, and then there was a small system design question. Nothing too complex, but the overall interaction wasn’t great. I got the sense that working with him day-to-day would feel the same, not very pleasant, a bit cold, just focused on tasks without much personal connection.
After the interview, they just disappeared. It’s been over a week now with no update, no rejection, nothing. Pretty unprofessional in my opinion.
You are tasked with designing a license server in Python to support annual licenses for tenants.
The system must scale to 100,000+ customers, with a strict 1-to-1 relationship between tenants and licenses.
Each license has a token limit and an expiration date set to one year from the license creation or update. You are given /setLicense and /execute endpoints.
Each license token can be consumed by both user and tenant requests.
Describe your data models, how you would efficiently handle 100K+ tenants, and how you would structure the endpoints and database interactions for scalability and reliability.
What database schema would you use? Where would you store it - NoSQL / SQL?
Let's say we have 100K requests for /execute. How do we achieve ACID?

Interview
Great product, but please be wary. They value "transparency" but if they sense you may not go with them, they will rescind verbal offers.
I was told by their CBO to expect an offer letter after the weekend (verbal offer), but they informed me with a 3am email the following Tuesday that they "brainstormed" and determined that they would go with another candidate.
Ironically, they then reposted the job on LI. Startups like this can be great for growth, but I find practices like this disingenuous.
Interview process was not hard, but their executive leadership seemed to have issues grasping the amounts of meetings needed to convert to qualified pipe. I've worked at large SaaS companies where it was common to set 5 or 6 meetings a week to get 2-3 qualified opps per week. I was rather shocked that their leadership acted like this was ridiculous figure.
There could be potential to really leave your mark at this company, but honestly feel like I dodged a bullet and am happy to move onto other opportunities!
