"I thought I was doomed, but an iPad saved the day" — feedback from a newly hired Meta engineer.
This is the story of a very ordinary developer's interview experience at Meta. No hundreds of LeetCode problems, no formal SQL optimization training, no big system design background. But he still passed one of Meta’s most critical technical interviews. His secret weapon? CSOAHELP’s real-time remote interview support.
As the team behind the service, we’re sharing this real story from our perspective, to show what our support actually looks like in action.
The candidate, Mr. L, was applying for a backend role at Meta. The second-round interview was a technical screen conducted online, combining SQL and Python problems. He reached out the day before the interview and said, “I’ve done some prep, but when it comes to the real thing, I freeze up—especially in English.”
We jumped in immediately. He used his main laptop to join the Meta interview, while our team connected silently through a secondary device—his iPad. Whenever he encountered difficulties, we used the iPad screen to send text-based cues: keywords, logical hints, and even pseudo-code structures when needed. All done silently without distracting the interviewer.
The first question was SQL-based.
"Existing customers can invite other people to sign up to the bookstore. Find the IDs of the top 5 customers, ordered by the average payment per book made by the people they invited."
It looked like a basic query, but the real challenge was in data modeling. Can you map the relationship between inviter and invitee? Can you accurately calculate downstream purchase behavior? Mr. L hesitated. We immediately prompted via iPad: “Start by identifying the inviter field. Does the data record the referral chain? Then, analyze orders placed by the invitees. Total the amount paid and count the books. Then compute the average payment per book.”
We added another reminder: “Don’t get lost in complex JOINs. Start with a clean logical model, then consider performance. Clarity comes first.” We also offered a clear SQL draft structure that he could paraphrase. Mr. L followed our cues, rewrote the logic, and got it right.
Then came the follow-up from the interviewer: “What happens if there are millions of users—will this query still perform well?”
We quickly suggested: “Mention indexing invitee IDs or using a subquery to pre-filter valid users before the JOIN.” Mr. L explained this clearly. The interviewer nodded in approval.
The second question was in Python.
"Write a function that returns the smallest nonnegative number which can be generated by using all the digits with odd values of a given number."
Input example: 10430. Expected output: 13. Mr. L looked puzzled and asked, “So we extract the odd digits and make the smallest number possible from them?”
We instantly sent instructions via iPad: “First, extract all digits that are odd. Second, sort them. Third, concatenate and return as an integer. Remember—all odd digits must be used once, no skipping or duplicating.”
To help him explain, we added a sample response: “I’ll extract all odd digits, sort them, and combine them to return the smallest number possible. No digit will be missed.”
Mr. L repeated this explanation and coded accordingly. The interviewer was satisfied, then followed up: “What if there are no odd digits in the number?”
We updated our cue immediately: “Consider the edge case—if no odd digits exist, return 0.” Mr. L added the check, and the answer was accepted.
The entire interview lasted about 40 minutes. Before each of Mr. L’s responses, we provided a clear strategy, language suggestions, and sometimes structural code hints. All he had to do was repeat or adapt what we gave him. He later told us, “It felt like you were scripting my answers—I just had to speak them out.”
The very next day, Mr. L received an invitation to the next interview round. Eventually, he got the Meta offer. He said, “I couldn’t have done it alone. Your help allowed me to show my real potential.”
This isn’t cheating—it’s about helping you express your existing skills to their fullest. We don’t feed you answers. We organize your thinking, structure your expression, and support your delivery.
Interviewers don’t just test your answers—they evaluate your reasoning, clarity, and communication. CSOAHELP ensures you don’t fall short in any of those.
We’re there when you freeze up—to give you keywords. When you go off track—to bring you back. When you can’t structure code—we outline it for you. When your thoughts get messy—we help untangle them.
You’re still you—just the best version of you.
Interviews aren’t exams. They’re pressure tests and communication challenges. If you’re prepping for Meta, Google, or Apple, don’t do it alone. Give yourself the boost you need. With CSOAHELP by your side, you can show up as your strongest self.
