Continuous 23 'Unfortunately email' but still struggling.

I am Machine Learning Engineer, having 6 year+ of experience in this domain and 10+ patents. Was working with a reputed multinational company in Bangalore(25LPA). My girlfriend was in the Netherlands so was finding for a Europe opportunity, Landed in Austria. but there was no company culture, frankly speaking, In Europe, the IT culture is worse than in India. They hired me for building a machine learning model and deploying it to production, but everything was on presentation, and I was only the team member in ML Team. I was writing unit test cases and really rough behavior from managers, Small German City - So no Indian - No friend - and with that Covid - Work from home. It was frustrating. And the salary was 55K Euro, Austria follows a 14-month salary structure and with high tax, my in-hand salary was less than my last Indian salary. Then I thought I should start exploring the opportunities in other European cities, mainly Amsterdam. was interviewed by 23 different companies(London, Amsterdam, Norway), around 60% of the opportunities, I was not selected for the visa and language problem(In Amsterdam, many places dutch speaking is mandatory - probably they wite the codes in the local language :P), Some of the famous experience I am sharing here: 1. Twitter London - October 2021: Coding interview: The interviewer asked me about the past works, recommendation engine, and NLP, I answered everything, he looked happy, then he asked me to have worked in unsupervised learning - I answered No, then he surprisingly asked me to write down the algorithm of 'k-means' from scratch. I was struggling, and he was not helping, the end of the interview - I executed the code. but after 2 days the recruiter sent me the 'Unfortunately you are not selected' email. 2. Amazon Dublin - November 2021: Coding Interview: the interviewer was asking me 3 very simple LC questions, I answered, I answered quickly, he asked me some stupid follow-up questions, but then he said himself the questions were stupid. Again after 2 days 'Unfortunately, you are not selected' email. Learning - if I will get a common question - I should act like :wooh difficult question - how can I solve it. 3. Booking Com - February 2022 : Amsterdam - hackerank passed, Coding passed, ML interviews passed (though the response was I am more inclined to the ML Scientist) but failed in system design interview. I asked the Recruiter to please provide me the specific feedback so that I can improve myself. he gave me 1 Con with 5 pros. In system design, the question was - I have to implement a multi-model monitoring dashboard. I used the LinkedList data structure to store the log. The advantage is - the write operation is super efficient, we always know the last pointer of the linked list, so it will be O(1), the disadvantage is - the read operation is not efficient - we need to traverse the whole linked list to find an element, so the complexity will be O(n) there is another concept to store the log into a binary tree because the write an read operation complexity is O(logN), it is a more write-based operation so I used a linked_list-based data structure over the binary tree. I told him twice, but it seems he has used an array for the same.Learning: Luck Matters 4. Mollie January 2022: In the JD, they asked, they were looking for tensorflow, experience with vertex AI. I built the home assignment solution with TFExtended, Kubeflow orchestrator which was using Vertex AI. The technical feedback was- I have good tensrflow experience but they are looking for a non-Tensorflow candidate. Learning: Sonam bewafa hai(A hindi meme) 5. Bol.com December 2021: They sent me a psychometric question and aptitude question set, I passed aptitude and the recruiter called me for the Fit interview. During the interview time, an interviewer found from the answers of the psychometric test that I don't own my tasks is totally wrong, So again an Unfortunately email. BTW in the interview time, I figured out they are solving the problem most novice way, I suggested it can be executed in a more efficient way. and the interviewer agreed. Learning: Fake Ego matters, India - or Europe, Everywhere. Observation: a. Indian and Chinese interviews should smile during the interview process, They are most hard to handle. It seems the GDP of the two countries depends on their foreign salary, Please smile. b. We talk about machine learning model explainability, there should be a proper transparent feedback explainability system. I have been working with a small startup with 65K Euro early salary. Not happy with the current ole..questions for the community: a. should I take a break and try out something else. b. should I continue the interview process or else start a 'motivational stand-up comedy' :P Thanks in advance..happy weekend Guys :) update: took 2 months break, got offers from PrimeVideo, Bol, and Elsevier #europe #tech #interview
