Round 2 : (Simulation Round)
They give you a problem to implement in 3 hours. We can use any language, any library or any framework.
I was given to develop a Broken Link Detector :
1. A URL good be given as seed URL
2. Fetch all the pages on this webpage
3. Check all broken links (those link are broken which give HTTP code other than 2xx OR 3xx)
4. If the link is not broken and is of the same domain, repeat steps 2-4 for this.
5. The final output should be txt file which stores all broken links corresponding to which webpage they occurred.
After the implementation, the interviewer saw the whole code, discussed the whole logic. Asked about optimizations which can be added.
I was even asked to implement the optimization (adding Thread Workers and concurrency) after going back and send him the code.
Round 3 : (with CTO)
Behavioral questions – Tell me about yourself, your projects, why do you join BSB, etc.
