Recyclable and Low Fat Products
A easy-tier problem at 89% community acceptance, tagged with Database. Reported in interviews at Bloomberg and 3 others.
You're staring at a database problem about filtering products. It sounds trivial until you realize you're joining or filtering across multiple boolean columns and the logic isn't quite what you'd write in Python. Bloomberg, Google, Meta, and Microsoft all ask this one. The acceptance rate sits at 89%, which means most people get it, but the ones who blank on SQL syntax or the WHERE clause logic end up that remaining 11%. StealthCoder runs invisible during your assessment and surfaces the exact query in seconds if you hit a wall on the joins or conditions.

Recyclable and Low Fat Products is the kind of problem that decides whether you pass. StealthCoder reads the problem on screen and surfaces a working solution in under 2 seconds. Invisible to screen share. The proctor sees nothing. Made by a working FAANG engineer who treats the OA the way companies treat hiring: as a game with rules you should know.
Get StealthCoderThis is a pure SQL filtering problem. You're selecting products that meet two criteria simultaneously, typically using AND logic in the WHERE clause. The trap isn't algorithmic complexity, it's SQL syntax or misunderstanding the schema. Candidates often overcomplicate with nested queries or subqueries when a simple WHERE clause with multiple conditions works. The real hedge here is knowing your database syntax cold: whether you're using MySQL, PostgreSQL, or another dialect matters for string matching or NULL handling. If you blank on the exact SELECT syntax or how to AND multiple boolean checks during a live OA, StealthCoder solves it in one keystroke.

Recyclable and Low Fat Products interview FAQ
Why does a database problem show up at companies like Google and Meta?+
SQL is a baseline skill for roles touching any backend system, even at scale. It's not a coding challenge, it's a competency gate. The low difficulty and high acceptance rate make it a screening question, not a differentiator. You either know it or you don't.
What's the actual trick here?+
There isn't one. You filter rows where both conditions are true using AND. The 'trick' is not overthinking it. Many candidates write complex subqueries or CASE statements when a clean WHERE clause solves it. Keep it simple.
Is this still asked even though acceptance is 89%?+
Yes. High acceptance doesn't mean it's not asked, it means most prepared candidates pass it. It's a screening question. Expect it at most of these companies if you interview with them.
How does this connect to real backend work?+
You're learning to read a schema and write precise filters. In production, you'll query product tables, user tables, and orders this way daily. This problem is the skeleton; production adds indexes, performance tuning, and complexity.
What if I freeze on the exact WHERE syntax during the OA?+
That's exactly what StealthCoder hedges for. You see the working query instantly, invisible to the proctor. No syntax stumble costs you the question.
