Interview Preparation Tips

Interview preparation tips for other job seekers - They took 5 rounds of interview. 3 of them were technical and had easy to moderate level of questions. Rest 2 were more of HR rounds.
After taking 5 rounds, they have the audacity of not even calling back, picking up the calls or providing us with any information. If you are not interested in taking the candidate then why waste their time?

Funniest part is that they are fully aware of what a rubbish organization it is. In the later rounds they talked about cost cutting, negative news around the company, and employee complaints for work life balance. However, they are great at gaslighting as well because they make these sound like employee problems not employer problems.

Tip 1 : Practice is they to success, every person will need a different path for preparation, the resources that you should use will depend upon your current expertise.
Tip 2 : For Machine Coding Rounds speed is key, you need to practice atleast 20 questions, Try to figure out techniques to common out code, code out your first question, and then spend good 2-3 hours in reducing no of lines and removing redundancy, try to note down methods you used to achieve less redundancy and for all the next questions you practice try to achieve that same quality from the beginning which will automatically increase your speed
Tip 3 : Do company wise preparation, look for interview experiences and try to map out commonly asked questions and categories of those questions and practice accordingly
