Specify the environment directly in the job description.
A strong SQL Developer interview should test query reasoning, schema design, performance, indexes, transactions, and production debugging.
Avoid relying entirely on syntax questions.
SQL syntax is easy to look up.
Understanding why a production query became slow is much harder.
Ask:
Walk me through the most technically challenging SQL or database system you've worked on.
Then ask:
Give the candidate:
Customers
Orders
Order Items
Products
Ask them to calculate revenue by customer.
Then add:
Include customers who placed no orders.
This tests whether they understand join semantics rather than memorizing definitions.
Ask:
Write or describe SQL that calculates a customer's seven-day rolling revenue.
Look for understanding of:
Ask:

A query filters by customer_id and then orders by created_at. How would you think about indexing it?
Look for reasoning around actual query access patterns.
Ask:
When can adding another index make the application worse?
Strong candidates should mention:
Ask:
A checkout process creates an order and updates inventory. The inventory update fails. What should happen?
Explore transaction boundaries and consistency.
Ask:
Two transactions intermittently deadlock in production. How would you investigate them?
Strong candidates should think about:
Ask:
Design the database for a multi-tenant SaaS application.
Explore:
There can be several valid architectures.
You're looking for tradeoff awareness.
Ask:
When would you use a CTE and when would you materialize intermediate data in a temporary table?
The candidate should discuss readability, reuse, indexing, and engine-specific behavior.
Ask:

The region has the perfect mix of everything you want in remote employees: English skills, shared time zones, hard-working, and depth of talent. They are already accustomed to working remotely for top US startups and Fortune 500 companies.
Absolutely! The US and Latin America have basically the same time zones. No Latin American city is more than two hours ahead of EST.
Every hire is sourced based on your exact needs. They will arrive ready to support your business right away. They can do basically any tasks done remotely, but we recommend starting them as support so your team has more bandwidth for high-value strategic tasks.
All types of roles - customer service, executive assistant, sales, accounting, email marketing, lead generation, content writers, operations, social media marketing, and more!
You can pay directly through us (most popular) or we can connect you with one of our payroll partners.
You don't have to deal with any American labor laws / taxes when hiring full-time remote contractors. They aren't US-based, so no visas or sponsorships to deal with either.
Pricing is one flat monthly rate per hire. The rate includes your teammate's compensation and South's service in a single consolidated invoice. It covers sourcing, vetting, payroll, compliance, ongoing support, and a free replacement if you ever need one. Rates vary by role and seniority. See our savings by role page for typical ranges, then we'll confirm an exact rate for your role.
There are no cancellation fees or minimum commitments, and you only pay if you make a hire.
Yes, we only recruit for full-time and we strongly recommend full-time hiring if you can. Stability (full-time & long-term) is highly sought after abroad. The top caliber candidates are only looking for full-time work.
You're also going to spend time training and getting them up to speed on your processes. It would be a waste to do that over and over again with new people all the time.
We recommend training new hires on one thing at a time.
For example, once they get up to speed on lead generation, you can add the next role writing blog posts or whatever you'd like. You can definitely overlap roles until you have enough work for multiple people.
The cost of living is much less in Latin American countries. Many of our employees are able to own homes, raise families, provide for their parents, and have in-home help of their own with their salaries.
If you aren't happy with your hire in the first 120 days, we will work with you to conduct a second round of search for the same role for free.
