Entegris interview questions

The interview process isn't appropriately designed. They will first conduct one round of interview, ask you to wait for indefinte period of time. Then suddenly, after a month, they will reach out to you saying that there are 4 more rounds of interviews. After scheduling these 4 rounds, suddenly they will consolidate one of the rounds and make the count 3. You appear for the 3 rounds and then wait for the feedback. Again, after two more weeks, you will receive a call stating that there are 2 more rounds (F to F) and a virtual one. You again appear for these 2 rounds making the total count of interviews to hit 6. After that you wait for an indefinite period of time to get a feedback. For me, out of many candidates, only 5 were shortlisted for the 2th to 4th rounds out of which only 2 including me were selected to appear for the 5th and 6th rounds. It has been >90 days that Entegris is still not sure whom to select! This is ultimately and aggressively disappointing. I would not recommend to go for interviews with this organization as it ultimately leads to sheer disappointment, wastage of time and effort you put in for those interviews.
