Full stack developer Interview Questions

3rd round interviewer was really rude, he didn't even repeat the problem stating that you should have listen on first time, he did not even explain the problem and asked me to understand the problem from code and tell me the solution. the experience was worst, I have not seen anyone in industry who refuse to repeat the problem.

Singleton pattern allow array to access a global point to ask for optimisation

Onsite: do a request to api and show results (javascript + HTML + css, no react or vue or angular); design system to save events of users; return k biggest int in array

The key in generic questions like this, is to make sure to cover the fundamentals. There's usually a back-and-forth with the interviewer. Might be worth doing a mock interview with one of the Spotify Full Stack Developer experts on Prepfully? Really helps to get some real-world practice and guidance. prepfully.com/practice-interviews

I came up with my own solution quickly that worked quite well (I missed one corner case) and overall did really well. However, I got a rejection because my solution was 'too simple' and 'did not work'. The interviewer kept pushing me towards the text book answer (probably the only thing they know) and they seem to expect the candidate to have the solution memorised and to just produce a text book answer. I think it was an extremely poor interview, as they didn't appreciate I managed to create an excellent solution on the spot without prior knowledge of this algorithm. Instead they were looking for someone who might not be a great problem solver but has memorised a bunch of useless algorithms that are never used in real life. The interview was called pair programming but it was just me coding, so it was not what I'd call pair programming which some other companies do really well.

There's quite an extended back and forth in actual interviews for questions like this, so nothing quite like real practice. The Prepfully Transferwise Full Stack Developer experts have actually worked in this role, so they're able to do an honest-to-God accurate mock, which really puts you through the paces. prepfully.com/practice-interviews

Discussed education and previous job

I 've resolved the test code but I was a bit slow ,then they didn't go forward with me in the afternoon. They didn't know I came from Verona!!! They were surprised! I asked Barbara if there was some refund for my expenses. She said they consider its only for students :-) no for worker engineers :-) and she didn't pay back anything. My expenses were around 200 euros. (flying and rent a room for 2 days ) Serious companies pay back expenses if they are very interesting to see candidates. Bad experience, I don't advice it to anyone, lost time and money!. They don't care you have flown from Verona and I've spent 3 days. If you are in London you could do it.

Working for a smaller team would give me the the potential to create great impact. There is further opportunity to grow and also be agile in our methods. Working for a larger team doesn't appeal to me - I'd rather be a voice and be in an environment where the work I am doing is genuinely influencing the direction of the team/company.
