IBM Front-End Developer interview questions

I was interviewed at Kochi IBM for the role of front end developer. The interview questions were based on Angular. The questions were harder compared to my interviews in other companies. Interviewers expect you to write down the code for interceptors and auth guards. They are not satisfied even if you explain its working in detail to them. Their major focus was on HTML and CSS rather than JavaScript or TypeScript, which is strange. They deliberately keep on interrupting while you are answering. I later came to know that the interviewers give more preference to the referral candidates of their colleagues so that the favor is returned for their referrals. So it is expected that they try to push you out and select their colleagues referral. HR doesn't respond if you are rejected. Interview experience was disappointing.
