Three questions asked. The test duration was 3 hours and was conducted on hackerearth. 1. Write a sql parser to properly parse queries for a particular table. The input will consist of several lines: the first line is of two values, N and M, separated by a comma. The next line has the names of the columns of the table. The next N lines will contain N rows of the table (each column delimited by a comma). After that, the next M lines will contain where clause of sql query which you are supposed to execute and return their output (one in each line). Table input will be in the following format: "ID","Name","Date" 1,"Narendra Moody","2014-10-23 12:21" . . . 100,"Rahul Pandey","2013-11-02 13:01" Query input will be given in following format: ID > 99 and Name = "Rahul Pandely" You are supposed to evaluate query and print the number of rows that come under the criteria. For example solution for above query will be 1.
Sample Input (Plaintext Link) 6, 1 "ID","Name","Date","Score" 1,"Aditya Moody","2014-10-23 11:55",20 2,"Utsav Moody","2014-10-24 15:18",21 3,"Jon Doe","2014-10-23 02:51",62 4,"Foo Bar","2014-10-23 12:00",98 5,"Rahul Moody","2014-10-23 12:31",61 6,"Umang JarJar","2014-10-23 11:21",33 Date > "2014-10-23 12:00"
Sample Output (Plaintext Link) 2 Time Limit: 5 sec(s) for each input file. Memory Limit: 256 MB Source Limit: 1024 KB Marking Scheme: Marks are awarded if any testcase passes. Allowed languages: C, C++, Clojure, C#, Go, Haskell, Java, JavaScript, Objective-C, Perl, PHP, Python, Ruby 2. Given HTTP request or response headers, write a program that prints the "request" or "response" based on the input. Also, In case of a "response", print the following: - Response code - Content-Type of the body In case of a "request", print the following: - Value of Accept-Language header, if present - Resource requested For eg: Given the input: GET /index.html HTTP/1.1 Host: www.browserstack.com The output will be: request /index.html Sample Input (Plaintext Link) GET /index.html HTTP/1.1 Host: www.browserstack.com Sample Output (Plaintext Link) request /index.html Time Limit: 5 sec(s) for each input file. Memory Limit: 256 MB Source Limit: 1024 KB Marking Scheme: Marks are awarded if any testcase passes. Allowed languages: C, C++, Clojure, C#, Go, Haskell, Java, JavaScript, Objective-C, Perl, PHP, Python, Ruby 3. You will be given lines of a web server log as shown in example below. You are supposed to parse it and for all the HTTP codes that occurred in the file, print in each line the HTTP code that occurred followed by how many times did it occur.
Output should be sorted in descending order of occurrences.

About Browserstack Interview Reports
This question was reported by a candidate who interviewed at Browserstack. LeakCode aggregates interview reports from 10+ sources, including 1Point3Acres, Glassdoor, LeetCode Discuss, Blind, Reddit, Indeed, and Nowcoder. Each report is translated where necessary, deduplicated against existing entries, and tagged by company, role, round type, and reporting date.
Use this question as one calibration data point, not a memorization target. Companies typically rotate their question pools every 2-4 months; the exact wording of a 2024 question may differ from what you encounter today. The underlying pattern, difficulty level, and follow-up depth at Browserstack are the higher-signal extractions to take from this report.
For broader preparation context, the Browserstack interview process typically includes a recruiter screen, one or two technical phone screens, and a 4-5 round on-site loop covering coding, system design (at L4+ levels), and behavioral. Reports tagged on LeakCode show the round-by-round distribution and typical difficulty calibration. To browse questions filtered by round type and seniority, use the company hub linked above.
How To Practice This Type of Question
Solve similar problems on LeetCode under timed conditions (25-35 minutes per medium difficulty). The goal is pattern recognition: recognize the underlying technique (sliding window, two-pointer, BFS, memoized recursion, etc.) within 60-90 seconds of reading. Strong candidates verbalize their hypothesis out loud before coding, then iterate based on feedback. Weak candidates dive into implementation immediately, lose time on the wrong approach, and run out of time for follow-ups.
Companies update their question pools every 2-4 months. The exact wording of any given question may have been retired by the time you interview. Focus your prep on the pattern, not the specific problem. The patterns that appear in Browserstack reports consistently are the ones worth investing in; one-off niche problems are not.
During Your Browserstack Round
Apply the standard interview round template: clarify requirements (2-3 minutes), state your approach out loud and confirm direction with the interviewer (3-5 minutes), code with narration (15-25 minutes), test with concrete examples including edge cases (5 minutes), discuss optimization or trade-offs if time permits (5 minutes). This template is universally accepted across FAANG and adjacent companies; deviating from it produces weaker interviewer feedback signal.
The single most predictive failure mode in Browserstack reports tagged "no hire": not asking clarifying questions. Interviewers are explicitly trained to weight this. Strong candidates ask 3-5 clarifying questions even on problems that look obvious; weak candidates dive into code immediately. The clarifying-question check is often the first signal recorded in the interviewer's written notes.
