I had an interview with a start-up company for the position of data-scientist. I started by describing my previous experiences. I described the problem then solutions that I applied. then they started by asking me technical questions:
- What are the drawbacks of Principal component analysis? I answered correctly
- How can you link c++ and java? I also answered correctly
They also asked me are you ready to take the risk of leaving your previous work and coming to a start-up which is full of risks. I answered yes I am ready to take that risk because the end result will be good.
The interview was done with the co-founders of the company. One is specialized in Machine learning and the other in programming more specifically Java. The interview lasted for 40 minutes. As I mentioned earlier it went really smooth. In the end they asked for the Salary. I said that I want $40k per year.
The next day: They called me and extended a job offer with my requested Salary ($40k).
In the second start-up so far I have had two interviews: one with the Human resources the second with a Researcher in machine learning. I nailed all the questions. Next week I have another interview with the last boss (The most difficult one) If I pass the last boss they will offer a position.
I didn't chicken out and I passed the interview yesterday with a professor. The questions were brutal. It was good though and they contacted me today to go to their startup and meet the team.
I learned something important. The professor told me That I have 2/3 knowledge but I lack 1/3 theory in Machine learning. I contradicted him and he cornered me. In the end he told me I care for you this is why I told you this and all what I had to say is yes you are right I'll improve myself. It was really interesting and humbling.
I did like it. It gave me self confidence and I knew my limits. I'll be going next Monday to their startup to meet the team.
- Is there something fishy with the first company? I really found it weird that it went so fast.
- Would you do go on with the second start-up and do the interview?
